ISL95872 Buck PWM Controller

PIN NUMBER SYMBOL DESCRIPTION 1 GND IC ground for bias supply and signal reference. 2 RTN Negative remote sense input of VOUT. If resistor divider consisting of RFB and ROFS is used at FB pin, the same resistor divider should be used at RTN pin, i.e. keep RFB1 = RFB, and ROFS1 = ROFS. 3 .

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.
