65V, 1A, 2MHz Synchronous Step-Down Regulator with 20ns minimum on pulse - BD51180TL (Under Development)

BD51180TL is a current mode synchronous DC/DC converter integrating high voltage tolerant POWER MOSFETs. The wide range input up to 65V and the very short minimum on pulse down to 20ns enables direct conversion from 48V battery to 3.3 V at 2.1 MHz operation.
