1.3A, 5V Input, 1.4MHz Synchronous Buck Converter

Overview

TopologyBuck Converter
Input voltage2.9-5.5 V
Output 10.6 V
IC revisionA.4

Description

The APW7408B is a 1.3A synchronous buck converter that uses current-mode control scheme to convert wide input voltage of 2.9V to 5.5V to outputs as low as 0.6V while providing excellent output voltage regulation.The APW7408B operates in Force PWM mode operation.The internal switching frequency is set at 1.4MHz while the EN/SYNC pin supports external clock synchronization, and is also equipped with Power-on-reset, internal soft start and complete protections (under-voltage, over-voltage,over temperature and current-limit) into a single low cost SOT-23-5 package. The IC also provides output capacitor discharge when it is disabled via the internal low side MOSFET.

Features

  • Typical 0.6V Internal Reference Voltage
  • Force PWM Mode Operation
  • Stable with Low ESR Ceramic Capacitors
  • Power-On-Reset Detection on VIN
  • Integrated Soft Start and Output Discharge
  • Over-Temperature Protection
  • Over Voltage Protection
  • Under Voltage Protection
  • High/ Low Side Current Limit
  • Enable/Shutdown Function
  • Small SOT-23-5 packages
  • Lead Free and Green Devices Available (RoHScompliant)

Typical applications

  • Portable Instrument
  • Set-Top Box, DSL, Switch HUB
  • Notebook Computer & UMPC, LCD Monitor/TV
