JWH5123 Preliminary Specifications Subject to Change without Notice 65V/3.5A Asynchronous Step-Down Converter DESCRIPTION The JW®H5123 series are current mode monolithic buck switching regulators. Operating with an input range of 4.5V~65V, the JWH5123 series delivers 3.5A 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. Current mode control provides tight load transient response and cycle-by-cycle current limit. The JWH5123 series guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
