Product Details

LM25184QNGURQ1 is an AEC-Q100 automotive primary-side-regulated flyback converter in an eight-pin NGU WSON package with an integrated 65-V, 4.1-A power MOSFET.

It accepts 4.5 to 42 V at the input and supports isolated output power up to 15 W, fitting auxiliary rails that need galvanic separation from the vehicle supply.

The controller samples the reflected flyback voltage on the primary side, eliminating both an optocoupler and a transformer auxiliary winding from the regulation loop.

Boundary-conduction operation and the stated load-and-line regulation better than ±1.5 percent help set transformer and output-tolerance requirements before a board layout is committed.

Its wettable-flank WSON package and -40-to-150-degree-C junction range affect solder inspection and thermal review for compact automotive converters.
