LTC3803 Flyback DC/DC Controller

The LTC®3803 is a constant frequency current mode ﬂyback controller optimized for driving N-channel MOSFETs in high input voltage applications. Constant frequency operation is maintained down to very light loads, resulting in less low frequency noise generation over a wide range of load currents. Sl.
