Typical Application

Description

The LTM®8025 is a 36V_IN, 3A step down μModule® (power module) converter. Included in the package are the switching controller, power switches, inductor and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8025 supports an output voltage range of 0.8V to 24V and a switching frequency range of 200kHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.

The LTM8025 is packaged in a thermally enhanced, compact (9mm × 15mm) and low profile over-molded land grid array (LGA) and ball grid array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8025 is available with SnPb (BGA) or RoHS compliant terminal finish.
