LTM4661

15V, 4A Step-Up

µModule Regulator

FEATURES

DESCRIPTION

The LTM^®4661 is a synchronous step-up switching mode

µModule^®(powermodule)regulatorina6.25mm×6.25mm

× 2.42mm BGA package. Included in the package are the

switching controller, power FETs, inductor and all support

components. Operating over an input voltage of 1.8V to

5.5V, down to 0.7V after start-up, the LTM4661 regulates

anoutputvoltageof2.5Vto15Vsetbyanexternalresistor.

It provides up to 4A switch current. Only bulk input and

output capacitors are needed.

Complete Solution in <1cm (Single-Sided PCB) or

0.5cm (Dual-Sided PCB)

Input Voltage Range: 1.8V to 5.5V, Down to 0.7V
