LTM4656/LTM4656-1

Synchronous Boost µModule Regulator

with Input-Output Short Protection

FEATURES

DESCRIPTION

The LTM^®4656 is a complete high efficiency boost

µModule^®(power module) regulator with the switch-

ing controller, power FETs, inductor, and all supporting

components. Only a few input and output capacitors are

needed. Operating over an input voltage range of 4.5V to

28V, the LTM4656 supports an output voltage range of 6V

to 36V, set by a single external resistor. Its high efficiency

design delivers up to 5A continuous output current. An

in-line protection circuit sets the maximum input current,

and will trip off the input power if exceeded and retry (see

Typical Applications section).

Complete Boost Switch Mode Power Supply

Wide Input Voltage Range: 4.5V to 28V

Output Voltage Range: 6V to 36V

4A Continuous Output Current (12V , 24V

)

OUT

2% Maximum Total Output Voltage Regulation

Over Load, Line and Temperature

Input Disconnect in Shutdown

Inrush Current Limit

External Frequency Synchronization

Programmable Frequency (350kHz to 780kHz)

Parallel Current Sharing

Up to 98% Efficiency

The high density boost design can convert up to 180W

of output power.

Selectable Burst Mode^®Operation

In-Line Overcurrent Protection

Fault protection features include overtemperature pro-

tection, and overcurrent protection input referred with

auto-retry. The µmodule is offered in a space saving

and thermally enhanced 16mm × 16mm × 7.07mm BGA

package. The LTM4656 is Pb-free and RoHS compliant.
