1.3A, 5V Input, 1MHz Synchronous Buck Converter

Overview

TopologyBuck Converter
Input voltage2.9-5.5 V
Output 10.6 V
IC revisionA.2

Description

The APW7408 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 APW7408 operates in Automatic Skip/PWM Mode operation 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
  • Automatic Skip/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

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