SFA0002
SFA0002 is PWM Controller manufactured by Sanken.
Primary Side Regulation PWM Controller for Automotive Applications
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 bees light, the operation of IC bees the burst oscillation mode in order to improve the circuit efficiency.
By employing the primary side regulation, the IC realizes low ponent counts and design-friendliness, leading to downsizing and standardization of the power supply circuit.
