Monolithic Micropower PFM Step-Up DC-DC Converter Evaluation Board

Overview

The NCP1406 is a monolithic micropower PFM step-up DC-DC converter. This device is designed to boost single lithium or two cells AA/AAA battery voltage up to 25 V (with internal MOSFET) output for handheld applications. Target applications include OLED Power, White LED Drivers, and LCD Bias. In addition to standard boost converter topologies, this device can be configured for voltage-inverting and step-down applications. This device is available in space-saving thin SOT23-5 (TSOP-5) package. With its small footprint, the device is also ideal for generating a boosted voltage from a 3.3 V or 5.0 V power rail.

There are 2 versions of the demo board that have been preconfigured to generate a voltage of 25V or 15V.

  • 85% Efficiency at VOUT = 25 V, IOUT = 25 mA, VIN = 5.0 V
  • Low Operating Current of 15 uA (Not Switching)
  • Low Shutdown Current of 0.3 uA
  • Low Startup 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
  • Output Voltage Soft-Start
  • Feedback Pin Open/Short Circuit Protection
  • Input Under-voltage Lockout
  • Thermal Shutdown
  • Low Profile and Minimum External Parts
