Description

The FAN3506 is complete housekeeping circuitry for use in the secondary side of PC SMPS (Switched Mode Power Supply). It contains various functions, which are over voltage protection including two extra protection inputs, power supply on/off delay control and power good signal generator. Especially, it contains a programmable shunt regulator for output feedback and the reference voltage is trimmed to ±2%. The FAN3506 is available in 16-DIP.
