General Description

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.

Slope compensation can be programmed with an external resistor.
