4-Phase Monolithic Synchronous Boost Converter Delivers 2.5A
with Output Disconnect in a 5mm × 5mm QFN Package
Design Note 332
David Salerno
Introduction 5A peak current capability and an effective switch RDS(ON)
The LTC3425 is the industry’s first 4-phase, monolithic of 40m (NMOS) and 50m (PMOS), the LTC3425 is
synchronous boost converter. It can start up with as little capable of efficiently delivering 2.5A load current from a
as 1V and operate with inputs up to 4.5V. The output 0.8mm maximum profile, 32-pin 5mm × 5mm QFN
