UCC19412 Datasheet Low Power Synchronous Boost Converter

Manufacturer: Unitrode

Overview: Low Power Synchronous Boost Converter application INFO available UCC19411/2/3 UCC29411/2/3.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The UCC39411 family of low input voltage, single inductor boost converters is optimized to operate from a single or dual alkaline cell, and steps up to a 3.3V, 5V, or adjustable output at 200mW.

The UCC39411 family also provides an auxiliary 7V output, primarily for the gate drive supply, which can be used for applications requiring an auxiliary output, such as 5V, by linear regulating.

The primary output

Key Features

  • 1V Input Voltage Operation Start-up Guaranteed under FULL Load on Main Output, and Operation Down to 0.5V.
  • 200mW Output Power at Battery Voltages as low as 0.8V.
  • Secondary 7V Supply from a Single Inductor.
  • Output Fully Disconnected in Shutdown.
  • Adaptive Current Mode Control for Optimum Efficiency.
  • High Efficiency over Wide Operating Range.
  • 6µA Shutdown Supply Current.
  • Output Reset Function with Programmable Reset Period DE.
