The ISL62875 is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersils Robust Ripple Regulator (R3) TechnologyTM. The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL62875 is a low-cost solution for applications requiring dynamically selected slew-rate controlled output voltages. The soft-start and dynamic setpoint slew-rates are capacitor programmed. Voltage identification logic-inputs select four resistor-programmed setpoint reference voltages that directly set the output voltage of the converter between 0.5V to 1.5V, and up to 3.3V using a feedback voltage divider. Robust integrated MOSFET drivers and Schottky bootstrap diode reduce the implementation area and component cost.

Intersils R3 TechnologyTM combines the best features 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-load conditions such as system standby
