LTC3803ES6-5#TRPBF

LTC3803ES6-5#TRPBF

  • Product Code: LTC3803ES6-5#TRPBF
  • Availability: In Stock

The LTC3803ES6-5#TRPBF 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 LTC3803ES6-5#TRPBF 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, the LTC3803ES6-5#TRPBF can also be powered from a high VIN through a resistor, due to its internal shunt regulator. An internal undervoltage lockout shuts down the LTC3803ES6-5#TRPBF when the input voltage is too low to provide sufficient gate drive to the external MOSFET.


The LTC3803ES6-5#TRPBF is available in a low profile (1mm) 6-lead SOT-23 (ThinSOT™) package.
