UCD7242 Datasheet Digital Dual Synchronous-buck Power Driver

Manufacturer: Texas Instruments

Overview: UCD7242 .ti. SLUS962B – JANUARY 2010 – REVISED AUGUST 2012 Digital Dual Synchronous-Buck Power Driver Check for Samples:.

General Description

The UCD7242 is a plete power system ready to drive two independent buck power supplies (see Figure 1).

High side MOSFETs, low side MOSFETs, drivers, current sensing circuitry and necessary protection functions are all integrated into one monolithic solution to facilitate minimum size and maximum efficiency.

Driver circuits provide high charge and discharge current for the high-side NMOS switch and the low-side NMOS synchronous rectifier in a synchronous buck circuit.

Key Features

  • 1.
  • Fully Integrated Power Switches With Drivers for Dual Synchronous Buck Converters.
  • Full Compatibility With TI Fusion Digital Power Supply Controllers, Such as the UCD92xx Family.
  • Wide Input Voltage Range: 4.75 V to 18 V Operational Down to 2.2 V Input With an External Bias Supply.
  • Up to 10A Output Current per Channel.
  • Operational to 2 MHz Switching Frequency.
  • High Side Current Limit With Current Limit Flag.
  • Onboard Regulated 6 V D.
