JW5117 Preliminary Specifications Subject to Change without Notice 45V/5A Asynchronous Step-Down Converter DESCRIPTION The JW®5117 is a current mode monolithic buck switching regulator. Operating with an input range of 4.8V~45V, the JW5117 delivers 5A 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 transient response and cycle-by-cycle current limit. The JW5117 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, output over-voltage protection and input under voltage lockout.
