ISL62875 - PWM DC/DC Controller

Renesas

Datasheet Details

of both fixed-frequency and hysteretic PWM control. The PWM frequency is 500kHz during static operation, becoming variable during changes in load, setpoint voltage, and input voltage when changing between battery and AC-adapter power. The modulators ability to change the PWM switching frequency during these events in conjunction with external loop compensation produces superior transient response. For maximum efficiency, the converter automatically enters diodeemulation mode (DEM) during light-l.
