General Description

SFL100 is a highly integrated solution for SMPS applications requiring a dual control loop to perform CV (constant voltage) and CC (constant current) regulation.

SFL100 has wide VCC operating range (3.3V to 36V).

The IC integrates a 1.21V voltage reference with ± 1% accuracy, two Op-Amps (with OR-d open drain outputs), and a low side current sensing circuit.

Key Features

  • Secondary Side Constant Voltage (CV) and Constant Current (CC) Control.
  • Wide VCC Operating Range (3.3V to 36V).
  • Trimmed 1% Internal Voltage Reference.
  • Wired or Open-Drain Output Stages.
  • Low External Component Count.
  • Low Supply Current: 0.5mA.
  • Easy Frequency Compensation.
  • Operating Temperature Range: -40 to 125℃.
