Microchip NX9548CMTR | Demoboard NX9548

Overview

TopologyBuck Converter
Input voltage4.5-24 V
Output 124 V / 9 A

Description

The NX9548 is buck switching converter in multi chip module designed for step down DC to DC converter in portable applications. It is optimized to convert single supply up to 24V bus voltage to as low as 0.75V output voltage. The output current can be up to 9A.It can be selected to operate in synchronous mode or non-synchronous mode to improve the efficiency at light load. Constant on time control provides fast response, good line regulation and nearly constant frequency under wide voltage input range. Over current protection and FB UVLO followed by latch feature.Other features includes: internal boost schottky diode, 5V gate drive capability, power good indicator, over current protection, over voltage protection and adaptive dead band control. NX9548 is available in 5x5 MCM package.

Features

  • Internal Bootstrap Schottky Diode
  • Ultrasonic Mode Operation Available
  • Bus Voltage Operation From 4.5V to 24V
  • Less Than 1uA Shutdown Current with Enable Low
  • Excellent Dynamic Response with Constant On Time Control
  • Selectable Between Synchronous CCM Mode and Diode Emulation Mode to Improve Efficiency at Light Load
  • Programmable Switching Frequency
  • Current Limit and FB UVLO with Latch Off
  • Over Voltage Protection with Latch Off

Typical applications

  • UMPC, Notebook OCs and Desknotes
  • Tablet PCs/Slates/Hand-Held portable Instruments
  • On Board DC to DC Such as 12V to 3.3V, 2.5V or 1.8V
