JW5121 - JoulWatt

JW5121 60V/2A Asynchronous Step-Down Converter

The JW®5121 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5V~60V, the JW5121 delivers 2A of continuous output current with an integrated high side N-Channel MOSFET. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load tra.
