ISL62881HRTZ-T - Renesas Electronics

Description: The ISL62881 is a single-phase PWM buck regulator for microprocessor or graphics processor core power supply. It uses an integrated gate driver to provide a complete solution. The PWM modulator of ISL62881 is based on Renesas' Robust Ripple Regulator (R3) technology™. Compared with traditional modulators, the R3™ modulator commands variable switching frequency during load transients, achieving faster transient response. With the same modulator, the switching frequency is reduced at light load, increasing th
