DESCRIPTION

The LTM?4712 is a high efficiency buck-boost μModule

? (micromodule) regulator. The switching controller,

power switches, inductor and support components are

included in the package. The complete design requires

only a few external components, including a resistor to

set frequency, a resistor to set output voltage, input, and

output capacitors, a sensing resistor to achieve input or

output average current regulation. The LTM4712 operates

over a 5V to 36V input voltage range and can regulate

output voltages between 1V and 36V.

The LTM4712 supports selectable forced continuous

mode (FCM)/pulse-skipping mode (PSM) operation. The

current mode control enables a fast transient response

to line and load changes without sacrificing stability. The

SYNC input and CLKOUT output allow easy synchronization.

It supports multi-phase parallel operation for high

power applications.

The LTM4712 is offered in a 16mm × 16mm × 8.34mm

ball grid array (BGA) package suitable for automated

assembly by standard surface mount equipment. The

LTM4712 is RoHS-compliant.
