DATASHEET ISL95872 Buck PWM Controller with Internal Compensation and External Reference Tracking FN7974 Rev 0.00 January 26, 2012 The ISL95872 is a Single-Phase Synchronous-Buck PWM controller featuring Intersil’s proprietary R4™ Technology. The R4™ modulator has integrated compensation, fast transient performance, accurate switching frequency control, and excellent light-load efficiency. These technology advances, together with integrated MOSFET drivers and a schottky bootstrap diode, allow for a high performance regulator that is highly compact and needs few external components. Differential remote sensing of the output voltage is an additional feature.
