8V Undervoltage Lockout Threshold Operating Junction Temperature from –40°C to 150°C Adjustable Slope Compensation Internal Soft-Start Constant Frequency 200kHz Operation ±1.
5% Reference Accuracy Current Mode Operation for Excellent Line and Load Transient Response No Minimum Load Requirement Low Quiescent Current: 240µA Low Profile (1mm) SOT-23 Package The LTC®3803-5 is a constant frequency current mode flyback controller optimized for driving 4.
5V and 6V-rated N-channel MOSFETs in high input voltage applications.
The LTC3803-5 operates from inputs as low as 5V.
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.
