Description

General part information

LTC3425 Series

The LTC3425 is a synchronous, 4-phase 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 0.045Ω and 0.05Ω, respectively. 4-phase operation greatly reduces peak inductor currents, 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, antiringing control, thermal shutdown, adjustable current limit, reference output and power good comparator.The LTC3425 is available in a small, thermally enhanced 32-pin QFN package.ApplicationsHandheld ComputersPoint-of-Load Regulators3.3V to 5V Conversion
