The LTC ? 3803 is a constant frequency current mode ?yback
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.
The LTC3803 provides ±1.5% output voltage accuracy and
consumes only 240μA of quiescent current. Ground-refer-
enced current sensing allows LTC3803-based converters

allows ef?cient operation at high input voltages. For sim-
plicity, the LTC3803 can also be powered from a high V IN
through a resistor, due to its internal shunt regulator. An
internal undervoltage lockout shuts down the LTC3803
when the input voltage is too low to provide suf?cient
