The ISL95870, ISL95870A, ISL95870B ICs are Single-Phase Synchronous-Buck PWM regulators featuring Intersil’s proprietary R4 Technology™.
The wide 3.
3V to 25V input
voltage range is ideal for systems that run on battery or AC-adapter power sources.
The ISL95870A and ISL95870B are low-cost solutions 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 (ISL95870A, ISL95870B) resistor-programm...
