LTC3803-3 - Flyback DC/DC Controller

General Description

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.

Key Features

  • n VIN and VOUT Limited Only by External Components n Adjustable Slope Compensation n Internal Soft-Start n.
  • 55°C to 150°C Operating Temperature Range n Constant Frequency 300kHz Operation n ±1.5% Reference Accuracy n Current Mode Operation for Excellent Line and Load Transient Response n No Minimum Load Requirement n Low Quiescent Current: 240μA n Low Profile (1mm) SOT-23 Package.
