Monolithic Power Systems MPQ18021A

100V, 2.5A, High-Frequency Half-Bridge Gate Driver

Overview

TopologyBuck Converter
Input voltage9-18 V
Output 14 A
IC revision1.0

Description

The MPQ18021A is a high-frequency, 100V, halfbridge,N-channel power MOSFET driver. Its lowside and high-side driver channels areindependently controlled and matched with a time delay of less than 5ns. Under-voltage lockout on both high-side and low-side supplies force theiroutputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.

Features

  • Drives N-Channel MOSFET Half Bridge
  • 115V VBST Voltage Range
  • On-Chip Bootstrap Diode
  • Typical 16ns Propagation Delay Time
  • Less Than 5ns Gate Drive Matching
  • Drives 1nf Load with 12ns/9ns Rise/FallTimes with 12V VDD
  • TTL Compatible Input
  • Less Than 150μA Quiescent Current
  • UVLO for Both High-Side and Low-Side
  • In SOIC8 Package

Typical applications

  • Avionics DC-DC Converters
  • Telecom Half-Bridge Power Supplies
  • Two-Switch Forward Converters;Active Clamp Forward Converters
