ISL62873 - PWM DC/DC Controller

Description

IC ground for bias supply and signal reference.

Enable input for the IC.

Features

  • Robust integrated MOSFET drivers and Schottky bootstrap diode reduce the implementation area and lower component cost. Intersil’s R3 Technology™ combines the best features of both fixed-frequency and hysteretic PWM control. The PWM frequency is 300kHz 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 conjunct.

The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL62873 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.
