JWH5140/JWH5140F 100V/0.6A Synchronous Step-Down Converter Preliminary Specifications Subject to Change without Notice DESCRIPTION FEATURES ® ® The JW H5140 and JW H5140F is a monolithic  6V to 100V operating input range buck switching regulator based on constant 0.6A output current on-time control (COT) for fast transient response.  Internal soft-start Operating with a wide input voltage range of  Adjustable switch frequency 6V~100V, the JW® H5140 and JW® H5140F  FCCM at light load (JWH5140F) delivers 0.6A of continuous output current with  PFM at light load (JWH5140) two integrated MOSFETs. Constant on-time  Input under voltage lockout control mode control provides tight load transient  Current run-away protection response and cycle-by-cycle current limit. At light  Short circuit protection loads, JWH5140 operates in low frequency to
