Boost Converter, PFM, DC-DC, 25 V, 25 mA

Overview

TopologyBoost Converter
Switching frequency1000 kHz

Description

The NCP1406 is a monolithic PFM step-up DC-DC converter. This device is designed to boost single Lithium or two cells AA/AAA battery voltages up to 25 V (with internal MOSFET) output for handheld applications. A pull-up Chip Enable feature is built-in with this device to extend battery-operating life. In addition to standard boost converter topologies, this device can be configured for voltage-inverting and step-down applications. This device is available in a space-saving TSOP-5 package. With its small footpring, the device is also ideal for generating a boosted voltage from a 3.3 V or 5.0 V power rail.

Features

  • 85% Efficiency at VOUT = 25 V, IOUT = 25 mA, VIN = 5.0 V
  • Low Operating Current of 15 µA (Not Switching)
  • Low Shutdown Current of 0.3 µA
  • Low Start−up Voltage of 1.8 V Typical at 0 mA
  • Output Voltage up to 25 V with Built−in 26 V MOSFET Switch
  • PFM Switching Frequency up to 1.0 MHz
  • Chip Enable
  • Feedback Pin Open/Short Circuit Protection
  • Output Voltage Soft-Start
  • Input Undervoltage Lockout
  • Thermal Shutdown
  • Low Profile and Minimum External Parts
  • Micro Miniature TSOP-5 Package
  • Pb-Free Package is Available

Typical applications

  • Personal digital assistants (PDA) / digital still camera / cellular telephone
  • hand-held games
  • LCD bias, white LED driver, OLED driver
  • handheld instrument
