LTC3803-5
Constant Frequency
Current Mode Flyback
DC/DC Controller in ThinSOT
FEATURES DESCRIPTION n The LTC®3803-5 is a constant frequency current mode
flyback controller optimized for driving 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. VIN and VOUT Limited Only by External Components
4.8V Undervoltage Lockout Threshold
Operating Junction Temperature from –55°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 …
