Intersil ISL62883HRTZ

Description
The ISL62883 is a multiphase PWM buck regulator designed for microprocessor core power supply. It utilizes interleaved phases to reduce output voltage ripple, providing enhanced system performance, thermal management, and efficiency. The regulator features two integrated gate drivers and an external gate driver for a complete solution. Its R3 modulator technology enables variable switching frequency during load transients for faster response and reduced efficiency at light loads.
