.. February 2006 LM25005 42V, 2.5A Step-Down Switching Regulator LM25005 42V, 2.5A Step-Down Switching Regulator General Description The LM25005 switching regulator Features all of the functions necessary to implement an efficient, high voltage buck regulator using a minimum of external ponents. This easy to use regulator includes a 42V, 160mΩ, N-channel MOSFET, with an output current capability of 2.5 Amps. The regulator control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line voltage feed-forward, cycle-by-cycle current limiting and ease of loop pensation. The use of an emulated control ramp...
