Product Overview

The LTC3425EUH#PBF is a 4-phase synchronous Boost Converter with output disconnect capable of operation below 1V input. It includes four N-channel MOSFET switches and four P-channel synchronous rectifiers for an effective RDS(ON) of 0.045R and 0.05R, respectively. 4-phase operation greatly reduces peak inductor current and capacitor ripple current and increases effective switching frequency, minimizing inductor and capacitor sizes. True output disconnect eliminates inrush current and allows zero load current in shutdown. External Schottky diodes are not required in most applications (VOUT<4.3V). Power saving Burst Mode® operation can be user controlled or left in automatic mode. Other features include 1µA shutdown current, programmable frequency with sync in and out, programmable soft-start, anti-ringing control, thermal shutdown, adjustable current limit, reference output and power good comparator.
  • 4-phase operation for low output ripple and tiny solution size
  • Output disconnect and inrush current limiting
  • Adjustable current limit
  • Synchronizable oscillator with sync output
  • Internal synchronous rectifiers
  • Power good comparator
  • Up to 95% high efficiency
  • 12µA Very low quiescent current
