Our Power Management ICs are designed to help you manage and control the power consumption of your devices. Our team of experts has designed these ICs with a focus on efficiency, reliability, and versatility. Our Power Management ICs can be used in a wide range of devices, from smartphones to industrial equipment.
DC TO DC CONVERSION
At GSME, we design advanced power management ICs that deliver efficient and reliable DC-to-DC conversion for today’s most demanding electronics — from smartphones to servers. Our solutions ensure seamless power delivery by converting high-voltage inputs into stable, energy-efficient output rails for processors, memory, and sensitive analog circuitry.
​
Our product portfolio includes high-efficiency Buck Converters with Voltage Mode, Current Mode, and Adaptive Constant On-Time (ACOT) control, Low Dropout (LDO) Regulators for precision voltage regulation, and multi-rail PMICs that integrate multiple power functions into a compact footprint. With built-in protection features and optimized thermal performance, GSME converters are engineered to enhance system stability, reduce energy loss, and accelerate time-to-market.
Key Features
Efficient Power Utilization
Our DC-DC solutions are engineered for high efficiency across all load conditions, from ultra-low-power modes to high-performance compute blocks. Our buck and LDO architectures minimize power loss, extend battery life, and reduce thermal footprint in embedded, consumer, and compute-oriented systems.
Enhanced Performance & Stability
Our converters deliver precise voltage regulation with fast transient response and low output ripple—essential for powering digital and sensitive analog subsystems. Built-in protections and advanced control architectures ensure robust performance across dynamic workloads.
Compact Design & Space Savings
Compact DC-DC solutions deliver efficient power while conserving board space. With fewer external components and a simplified layout, they help reduce BOM costs and support space-efficient system designs across a wide range of applications.
Advanced Control Modes for Precision Power Management
Modern DC-DC converters rely on advanced control architectures to deliver optimal performance, stability, and efficiency across a wide range of applications. At GSME, our power solutions integrate three primary control schemes—Voltage Mode, Current Mode, and Adaptive Constant On-Time (ACOT)—each tailored to specific system needs.
Key Features
Voltage Mode Control (VMC)
Voltage Mode Control regulates the output by comparing the output voltage to a reference and adjusting the duty cycle accordingly. It offers predictable and consistent performance, making it ideal for low-noise, steady-state applications. VMC is simple to implement and provides clean switching characteristics, which are essential for analog and RF circuits.
Current Mode Control (CMC)
Current Mode Control introduces an additional inner loop for current feedback, enhancing the system’s transient response and providing cycle-by-cycle current limiting. This improves load regulation under rapidly changing conditions and allows for easier current sharing in multiphase designs. CMC is often used in systems demanding fast response and improved stability under dynamic workloads.
Adaptive Constant On-Time (ACOT)
ACOT dynamically adjusts the on-time of each switching cycle based on real-time conditions, eliminating the need for traditional error amplifier compensation. This results in ultra-fast transient response, simplified compensation design, and high efficiency across a wide load range. ACOT maintains a relatively constant switching frequency to minimize EMI. It is well-suited for space-constrained, high-performance applications such as SSDs, DDR memory, and mobile devices, where power density and fast response are critical.
DYNAMIC SCALING VOLTAGE
Dynamic Scaling Voltage is an innovative technology that we integrate into our power management solutions at GSME. It allows for the dynamic adjustment of voltage levels in response to changing system requirements, optimizing power efficiency and enhancing overall performance in electronic devices.
​
With Dynamic Scaling Voltage, power is dynamically adjusted based on the workload or operational conditions of the device. This means that voltage levels can be scaled up or down as needed, resulting in improved power efficiency and reduced energy consumption. This is particularly beneficial for battery-powered devices where extended battery life is a critical factor.
​
Dynamic Scaling Voltage ensures that the device operates at the optimal voltage for the given workload. This results in enhanced performance, as the device can adjust its power consumption to match the required processing capabilities. It allows for efficient power allocation and resource utilization, leading to smoother operation and improved user experience.
POWER SEQUENCING
Power Sequencing is a critical aspect of power management integrated circuits (ICs) that governs the order and timing of power-up and power-down sequences in electronic systems. It ensures that the various power domains within a system are activated or deactivated in a controlled and synchronized manner, promoting reliable operation and preventing potential issues such as voltage spikes or current surges.
​
At GSME, we prioritize the implementation of robust Power Sequencing capabilities in our power management ICs. Our solutions are designed to provide precise and reliable control over power sequencing, offering a seamless integration of multiple power domains and ensuring the optimal operation of electronic systems.
Key Features
System Stability
Power Sequencing allows for the orderly activation and deactivation of power domains, ensuring that voltages and currents reach stable levels before other components are powered up. This prevents voltage or current mismatches that could compromise the stability and functionality of the system.
Component Protection
​By following a predefined power-up and power-down sequence, Power Sequencing protects the sensitive components within a system. It avoids exposing components to excessive voltage or current stresses, minimizing the risk of damage, premature wear, or functional degradation.
Enhanced Reliability
Proper Power Sequencing mitigates potential issues such as inrush currents, voltage overshoots, or undesirable interactions between different power domains. This contributes to improved system reliability, reducing the likelihood of unexpected shutdowns, glitches, or system failures.
Design Flexibility
Power Sequencing in PMIC offers design flexibility, allowing system designers to customize the power-up and power-down sequences to meet the specific requirements of their applications. This ensures compatibility with various components and subsystems within the system.
Power Management IC Solutions
At GSME, we deliver advanced power management ICs that combine precision, integration, and efficiency — engineered to meet the demands of compute, memory, analog, and battery-powered applications.
BUCK Converters
Designed for wide input voltage ranges and scalable output currents, our Buck regulators support both low-power and high-current rails. With options including Voltage Mode, Current Mode, and Adaptive Constant On-Time (ACOT) control, these converters provide fast transient response and high conversion efficiency across workloads — ideal for SoCs, embedded compute, and distributed power systems.
LDO Regulators
Our LDOs feature high PSRR, low output noise, and fast transient performance, making them ideal for post-regulation of noise-sensitive blocks like analog front-ends, clocks, and RF circuits. With a broad current support range, they deliver stable performance under dynamic conditions.
PMICs
Integrating multiple Bucks and LDOs, GSME’s multi-rail PMICs are tailored for platforms requiring tight voltage sequencing, thermal efficiency, and space optimization. These devices are designed for subsystems like SSD controllers, DDR memory, and compact edge compute modules, delivering high performance in a single, BOM-optimized footprint.
