SFA0002 - PWM Controller

General Description

The SFA0002 is the switching power supply IC for flyback circuit and has high accuracy error amplifier.

When the load of the power supply circuit becomes light, the operation of IC becomes the burst oscillation mode in order to improve the circuit efficiency.

Key Features

  • AEC-Q100 Qualified.
  • Current Mode Type PWM Control (Swithing frequency can be adjusted by external capacitor).
  • Reducing External Component Count by Primary Side Regulation.
  • Built-in High Accuracy Error Amplifier ( VFB = 2.5 V ± 2%,.
  • 40°C to 125°C).
  • Operation Mode Normal Operation: PWM Mode Light Load Operation: Burst Oscillation.
  • Soft Start Function (Startup time can be adjusted by external capacitor).
  • Drive Output Stop Functi.

Primary Side Regulation PWM Controller for Automotive Applications SFA0002 Data Sheet Description The SFA0002 is the switching power supply IC for flyback circuit and has high accuracy error amplifier. When the load of the power supply circuit becomes light, the operation of IC becomes the burst oscillation mode in order to improve the circuit efficiency. By employing the primary side regulation, the IC realizes low component counts and design-friendliness, leading to downsizing and standardization of the power supply circuit. Features ● AEC-Q100 Qualified ● Current Mode Type PWM Control (Swithing frequency can be adjusted by external capacitor) ● Reducing External Component Count by Primary Side Regulation ● Built-in High Accuracy Error Amplifier ( VFB = 2.
