Hot-selling and scarce MP2492DN-LF-Z 2A, 55V, 100kHz Step-Down Converter with Programmable Output Current Limit SOP-8

Product Descriptions

The MP2492 is a monolithic step-down switch  mode converter with a programmable output  current limit. It achieves 2A continuous output  current over a wide input supply range with  excellent load and line regulation.

The maximum output current can be  programmed by sensing current through the  inductor DC resistance (DCR) or an accurate  sense resistor.

MP2492 achieves low EMI signature with well  controlled switching edges.

Fault condition protection includes cycle-by-cycle  current limiting, and thermal shutdown.

The MP2492 requires a minimum number of  readily available standard external components.  The MP2492 is available in QFN10 (3mm x 3mm)  and SOIC8E packages.
