نظرة عامة على المنتج
The LM25005MHX/NOPB is a 42 V, 2.5 A step-down switching regulator from Texas Instruments with an integrated 160 mΩ N-channel MOSFET. Packaged in a 20-pin HTSSOP (PWP) with exposed pad, it operates from 7 V to 42 V input and provides an adjustable output down to 1.225 V. The current mode control with emulated inductor current ramp enables reliable operation at very small duty cycles.
