ISL62871, ISL62872
PWM DC/DC Controller With VID Inputs For Portable GPU Core-Voltage Regulator
FN6707 Rev 1.00 May 8, 2014
The ISL62871 and ISL62872 IC’s are Single-Phase Synchronous-Buck PWM voltage regulators featuring Intersil’s Robust Ripple Regulator (R3) Technology™. The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL62871 and ISL62872 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 two (ISL62871) or four (ISL62872) resistor-programmed setpoint reference voltages that directly set the output voltage of the converter between 0.
