The MPS PMIC series offers monolithic, integrated multi-rail power supply solutions, integrating synchronous buck, boost, buck-boost, electronic fuses (E-Fuses), load switches, linear regulator (LDO) – all within a single chip. Designed for multi-rail power supply systems in SoCs, FPGAs, SSDs, industrial control, in-vehicle infotainment, the Internet of Things (IoT) and AI edge modules, it significantly reduces the number of external components, PCB area and power supply design complexity, whilst balancing conversion efficiency, power sequencing control, circuit protection and low-noise performance.

I. Analysis of Core Functional Modules
1. Synchronous Buck Channel
Featuring an integrated low Rdson power MOSFET, this module employs a COT (Constant On-Time) or hybrid PWM/PSM control architecture. It supports multi-phase interleaved parallel operation and a 100% duty cycle, whilst automatically entering power-saving mode under light loads, achieving conversion efficiencies of up to 95% or higher. The switching frequency is configurable and supports spread-spectrum schemes to optimise EMI. Output currents range from amperes to high-current multi-phase channels, capable of powering the main core, DDR and peripheral logic rails. It features output over-voltage, under-voltage, current-limiting and thermal shutdown protection; certain automotive-grade models support the MPSafe functional safety workflow, meeting ASIL requirements.

2. Boost Channels
Supports boosting low input voltages to provide power, suitable for single-cell or multi-cell lithium-ion batteries and low-voltage battery pack applications, whilst maintaining a stable output voltage during input voltage sags. Features integrated loop compensation and supports soft-start to suppress inrush current; with a built-in reverse blocking mechanism, it can power loads such as backlights, sensors, RF modules and high-voltage interfaces. Supports switching between PWM forced mode and power-saving mode, reducing quiescent power consumption in standby conditions.

3. Buck-Boost Channel
The input voltage may be higher than, equal to, or lower than the set output voltage. It switches seamlessly between buck, pass-through and boost modes without mode-switching glitches, making it the preferred solution for battery-powered applications, USB PD and wide-voltage bus power supplies. Some models support bidirectional power transfer; when paired with an energy storage capacitor, they provide backup power in the event of a power cut. They are commonly used for SSD power-loss protection and power buses in portable devices. Built-in cycle-by-cycle current limiting adapts to wide voltage fluctuations. Monolithic...

4. Electronic Fuses (E-Fuses)
An intelligent power protection circuit that integrates high-precision current limiting, soft start, reverse current blocking, overvoltage protection and overtemperature shutdown, with thresholds configurable via resistors or I²C. Compared to traditional fuses, it supports automatic retry upon fault and fault status reporting, preventing downstream short circuits and surge damage to the main power supply and PMIC. The wide-voltage version supports bus voltages of up to 16 V and above, making it suitable for power input, backplane power supply and hot-swap port protection.

5. Load Switch
A power switch with ultra-low on-resistance, supporting independent enable control to manage the time-division power-on and power-off sequencing of individual power rails, and featuring a fast discharge function. With extremely low quiescent leakage current, it is suitable for cutting off power to idle peripherals during sleep mode, thereby reducing system standby power consumption. Some models integrate current-limiting detection and can be used in conjunction with E-Fuses to build a multi-level protection architecture, enabling zoned power management.

6. Linear Regulator (LDO)
Low-noise, high Power Supply Rejection Ratio (PSRR) linear channels, specifically designed to supply power to ripple-sensitive loads such as analogue circuits, clocks, RF circuits and ADCs. Supports low dropout operation, features low output noise and does not introduce switching EMI interference; can be used as a clean-up rail downstream of a switching power supply. The output voltage can be fixed or externally adjustable; some models feature enable and power-good (PGOOD) indicators.

II. General Capabilities of the Product Series
The entire series supports flexible power sequencing configuration. Channel enable sequences, output voltages, current-limit thresholds, switching frequencies and protection parameters can be configured via hardware pins or an I²C digital interface. Digital PMICs are accompanied by a host computer GUI tool, supporting online debugging and status reading. The Power Good (PGOOD) signal and interrupt output facilitate the host controller’s monitoring of the power supply status of each rail. The product range is divided into two main branches: industrial and commercial grade, and AEC-Q100 automotive grade. The automotive-grade versions adhere to the MPSafe™ design process, meeting functional safety and wide-temperature operating requirements. Packaging is primarily in small QFN packages, offering high power density and suitability for compact hardware designs.

III. Typical Application Scenarios
Suitable for systems requiring multiple supply lines at different voltages whilst simultaneously ensuring power protection and sequencing management, such as humanoid robot main controllers and sensor power supplies, industrial automation control boards, edge AI computing modules, in-vehicle domain controllers, solid-state drives (SSDs), wireless communication gateways, portable medical devices, and battery-powered handheld terminals.
