LTC3803
Constant Frequency
Current Mode Flyback
DC/DC Controller in ThinSOT
FEATURES DESCRIPTION n The LTC®3803 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. VIN and VOUT Limited Only by External Components
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 LTC3803 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 …
