ISL62870 Datasheet (Renesas) - PWM DC/DC Voltage Regulator Controller

ISL62870, PWM DC/DC Voltage Regulator Controller

ISL62870 PWM DC/DC Voltage Regulator Controller The ISL62870 IC is a Single-Phase Synchronous-Buck PWM voltage regulator featuring Intersil’s Robust Ripple Regulator (R3) Technology™.

The ISL62870 provides a low cost solution for compact high performance applications.The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC adapter power sources.

Resistor programmed output voltage setpoint and capacitor programmed soft-start delay allow for fast and easy implementa

ISL62870 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 duri
