Single-Phase PWM Regulator for IMVP-6.5? Mobile CPUs and GPUs

The ISL62881 is a single-phase PWM buck regulator for miroprocessor or graphics processor core power supply. It uses an integrated gate drivers to provide a complete solution. The PWM modulator of ISL62881 is based on Intersils 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 the regulator efficiency.
