TPS54334 Synchronous Buck Converter

28 V, 3 A, low quiescent supply current (Iq), synchronous monolithic buck converter with integrated MOSFETs from TI

Image of Texas Instruments TPS54334 Synchronous Buck ConverterTexas Instruments' TPS54334 is a 28 V, 3 A, IQ, synchronous monolithic buck converter with integrated MOSFETs. It enables small designs by integrating the MOSFETs and implementing current mode control to reduce external component count.

Efficiency is maximized through the integrated 128 mΩ/84 mΩ MOSFETs, IQ and pulse skipping at light loads. Using the enable pin, shutdown supply current is reduced to 2 µA by entering a shutdown mode. The TPS54334 provides accurate regulation for a variety of loads with an accurate 1.5% voltage reference over temperature.

Features  
  • Two 128 mΩ/84 mΩ MOSFETs for 3 A continuous output current
  • Power good
  • Low 2 µA shutdown quiescent current
  • 0.8 V internal voltage reference with ±1.5% accuracy over temperature
  • Fixed-frequency current mode control
  • Pulse skipping boosts efficiency at light loads
  • Overcurrent protection for both MOSFETs with hiccup mode for severe fault conditions
  • Thermal and overvoltage transient protection
  • Available in easy-to-use 8-pin SOIC PowerPAD™ and 10-pin SON
  • Monotonic start-up into pre-biased outputs
