Description
General part information
ISL62870 Series
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 implementation. Robust integrated MOSFET drivers and Schottky bootstrap diode reduce the implementation area and lower component cost. Intersil's R3Technology™ combines the best 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 during these events in conjunction with external loop compensation produces superior transient response. For maximum efficiency, the converter automatically enters diode-emulation mode (DEM) during light-load conditions such as system standby.
