LTC3803-3
Constant Frequency
Current Mode Flyback
DC/DC Controller in ThinSOT
FEATURES DESCRIPTION n The LTC®3803-3 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. n VIN and VOUT Limited Only by External Components
Adjustable Slope Compensation
Internal Soft-Start
–55°C to 150°C Operating Temperature Range
Constant Frequency 300kHz 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 APPLICATIONS Telecom Power Supplies
42V and 12V Automotive Power Supplies
