Overview

DATASHEET ISL95870, ISL95870A, ISL95870B PWM DC/DC Controller with VID Inputs for Portable GPU Core-Voltage Regulator FN6899 Rev.
1.
00 December 2, 2013 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-programmed setpoint reference voltages that directly set the output voltage of the converter between 0.
5V and 1.
5V, and up to 5V with a feedback voltage divider.
Compared with R3 modulator, the R4 modulator has equivalent light-load efficiency, faster transient performance, accurately regulated frequenc...
