JWH5140 - JoulWatt

JWH5140 100V/0.6A Synchronous Step-Down Converter

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 respo.
