Product Overview

The LTC3803ES6#TRMPBF 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. It provides ±1.5% output voltage accuracy and consumes only 240µA of quiescent current. Ground-referenced current sensing allows LTC3803-based converters to accept input supplies beyond the LTC3803's absolute maximum VCC. A micropower hysteretic start-up feature allows efficient operation at high input voltages. For simplicity, it can also be powered from a high VIN through a resistor, due to its internal shunt regulator. An internal under voltage lockout shuts down the controller when the input voltage is too low to provide sufficient gate drive to the external MOSFET.
  • Adjustable slope compensation
  • Internal soft-start
  • ±1.5% Reference accuracy
  • Current mode operation for excellent line and load transient response
  • No minimum load requirement
