Overview

DATASHEET ISL95873 Buck PWM Controller with Internal Compensation and External Reference Tracking FN8390 Rev 0.00 December 10, 2012 The ISL95873 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.

Key Features

  • External reference tracking.
  • Intersil’s R4™ modulator technology - Internal compensation - Fast, optimal transient response.
  • Input voltage range: 3.3V to 25V.
  • Output voltage range: 0.5V to 3.3V.
  • Precision voltage regulation - ±0.5% System accuracy over -10°C to +100°C.
  • Output voltage remote sense.
  • Fixed 300kHz PWM frequency in continuous conduction - Proprietary frequency control loop.
  • Automatic diode emulation mode for hig.
