Overview

NCP5269A Advance Information Synchronous Buck Controller with Auto Power Saving Mode and 2‐bit VID Inputs for System Agent NCP5269A is a synchronous buck controller that is optimized for converting the battery voltage or adaptor voltage into power supply rails required in notebook and desktop system.

NCP5269A is designed for applications requiring dynamically selected slew-rate controlled output voltages.

The soft-start is programmed by a single capacitor.

Key Features

  • Wide Input Voltage Range: from 3.3 V to 28 V.
  • Three Selectable Fixed Frequency 300 kHz, 400 kHz or 600 kHz.
  • 2-bit VID Selects Four Independent Voltages from 0.65 V to 1.5 V.
  • ±1.0% System Accuracy.
  • Differential Remote Output Voltage Sensing.
  • Soft Transient Control Reduces Inrush Current and Audio Noise.
  • Build-in Power-good Masking Supports Voltage Identification (VID) On-the-Fly Transients.
  • Simple Resistor Programming Voltag.
