Product Overview

The LTC3422EDD#PBF is a high-efficiency current-mode fixed frequency step-up DC-to-DC Converter with true output disconnect and inrush current limiting. The part is guaranteed to start up from an input voltage of 1V. The device includes a 0.20R N-channel MOSFET switch and a 0.24R P-channel MOSFET synchronous rectifier. The output voltage, switching frequency, soft-start time, Burst Mode® threshold and loop compensation are all simply programmed using tiny external passive components. Quiescent current is only 25µA during Burst Mode® operation, maximizing battery life in portable applications. The oscillator frequency can be programmed up to 3MHz and can be synchronized to an external clock applied to the SYNC pin. Other features include 1µA shutdown, short-circuit protection, anti-ringing control, thermal shutdown and current limit.
  • True output disconnect

  • Low noise
  • Programmable soft-start
  • Synchronizable oscillator
  • Guaranteed 1V start-up
  • Synchronous rectification - Up to 96% efficiency
  • 700mA Continuous/1A pulsed output current for Li-ion to 5V applications
