JWH5140/JWH5140F 100V/0.6A Synchronous Step-Down Converter DESCRIPTION The JWH5140 and JWH5140F is a monolithic buck switching regulator based on constant on-time control (COT) for fast transient response. Operating with a wide input voltage range of 6V~100V, the JWH5140 and JWH5140F delivers 0.6A of continuous output current with two integrated MOSFETs. Constant on-time control mode control provides tight load transient response and cycle-by-cycle current limit. At light loads, JWH5140 operates in low frequency to maintain high efficiency, while JWH5140F operates in continuous current mode for frequency sensitive application. The JWH5140 and JWH5140F guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
