Renesas ISL95808HRZ-T Dual-output PWM controller, CPU/GPU voltage regulator Overview
The ISL95808HRZ-T is a high-efficiency, dual-output PWM voltage regulator from Renesas Electronics, designed for powering high-performance CPUs, GPUs, and ASICs in computing and server applications. This advanced controller integrates two synchronous buck regulators with adaptive on-time (AOT) control, enabling ultra-fast transient response and high efficiency across a wide load range. It supports input voltages from 4.5V to 24V, making it compatible with 12V and 5V power rails in modern computing systems. Each output can deliver up to 30A of continuous current, providing robust power delivery for demanding processors and memory modules.
The ISL95808HRZ-T features digital PWM control with I²C/SMBus interface, allowing precise voltage margining, dynamic voltage scaling (DVS), and real-time monitoring of critical parameters such as output voltage, current, and temperature. The device includes integrated MOSFET drivers, reducing external component count and simplifying PCB layout. Its adaptive voltage positioning (AVP) optimizes transient performance while minimizing output capacitance requirements. The chip also provides comprehensive protection features, including over-voltage (OVP), under-voltage (UVP), over-current (OCP), and thermal shutdown, ensuring system reliability under fault conditions.
This power controller is particularly suited for data center servers, high-end workstations, and AI acceleration hardware, where power efficiency and precise voltage regulation are critical. It operates over an industrial temperature range (-40°C to +105°C) and comes in a compact 40-pin QFN package with exposed thermal pad for effective heat dissipation. The ISL95808HRZ-T's programmable switching frequency (200kHz to 1MHz) allows designers to balance efficiency and component size, while its phase interleaving capability reduces input ripple current.
