Product Overview

The LTC3803ES6-3#PBF 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. The LTC3803-3 provides ±1.5% output voltage accuracy and consumes only 240µA of quiescent current. Ground referenced current sensing allows the controller based converters to accept input supplies beyond the LTC3803-3'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 undervoltage 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
