36V, 12A Step-Up/Step-Down Buck-Boost μModule Regulator

The LTM4712 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.
