Description

PMP7797 is a wide-input SEPIC converter designed for automotive applications. This design uses the LM25037Q push-pull controller as an interleaved boost, which incorporates two gate drivers for controlling two sets of MOSFET switches. The input is 12V nominal with a working range of 6V at cold crank to 42V at load dump. An auxiliary soft-start circuit is incorporated into the design, as well as input and output LC filters. At higher input voltage this SEPIC is capable of higher output current as shown by the typical efficiency plot.
