Product Summary

The ISL6269CRZ is a Single-Phase Synchronous-Buck PWM controller featuring Intersil Robust Ripple Regulator (R3) technology that delivers truly superior dynamic response to input voltage and output load transients. Integrated MOSFET drivers, 5V LDO, and bootstrap diode result in fewer components and smaller implementation area. The ISL6269CRZ has a 1.5ms digital soft-start and can be started into a pre-biased output voltage. A resistor divider is used to program the output voltage setpoint.
