TPS56425x 3-V to 17-V Input, 4-A, Synchronous Buck Converters in SOT-563 Package

Overview

TopologyBuck Converter
Input voltage3-17 V
Output 110 V / 4 A

Description

The TPS56425x is a simple, easy-to-use, high efficiency, high power density, synchronous buck converter with input voltage ranging from 3 V to 17 V and supports up to 4-A continuous current at output voltages between 0.6 V and 10 V.The TPS56425x employs D-CAP3 control mode to provide a fast transient response and to support low-ESR output capacitors with no requirement for external compensation. The device can support up to 97% duty cycle operation. Integrated bootstrap capacitor helps achieve single layer PCB and can save total BOM cost.

Features

  • 3 V to 16 V input voltage range
  • 0.6 V to 7 V output voltage range
  • Up to 4 A output Current
  • ECO mode
  • Fast transient response

Typical applications

  • WLAN/Wi-Fi access point, switch, router, Pro-audio, surveillance, drone
  • TV, STB and DVR, smart speaker
