Typical Application

Description

The LTM®8032 is an electromagnetic compatible (EMC) 36V, 2A DC/DC step-down μModule® (power module) regulator designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controller, power switches, inductor, filters and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8032 supports an output voltage range of 0.8V to 10V, 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 low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.

The LTM8032 is packaged in a thermally enhanced, compact and low profile overmolded land grid array (LGA) and ball grid array (BGA) packages suitable for automated assembly by standard surface mount equipment. The LTM8032 is available with SnPb (BGA) or RoHS compliant terminal finish.
