LTC3803-3 - Constant Frequency Current Mode Flyback DC/DC Controller In ThinSOT

The LTC3803-3 is a constant frequency current mode flyback controller optimized for driving 6V-rated 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 240A of quiescent current. Groundreferenced current sensing allows LTC3803-3-based converters to accept input supplies beyond the LTC3803-3s absolute maximum VCC. A micropower hysteretic start-up feature allows efficient operation at high input voltages. For simplicity, the LTC3803-3 CAN also be powered from a high VIN through a resistor, due to its internal 9.4V Shunt Regulator An internal undervoltage lockout shuts down the LTC3803-3 when the input voltage falls below 4.4V, guaranteeing at l 4ea east 4.4V of Gate drive to the external MOSFET
The LTC3803-3 is available in a low profile (1mm) 6-lead SOT-23 (ThinSOTTM) package.
