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.

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.
