KA3501-PC switching power supply monitoring IC
KA3501 is a SMPS (Switching Power Supply) on the secondary side of the complete housekeeping circuit used. This IC (Integrated Circuit) contains a precision voltage reference, protection circuits and a power good signal generator. It also has a high current drive output combined with an external "skid" thyristor. The reference voltage is trimmed to the correct output voltage to ±2% (+5 V/+12 V) and the power good signal generator is monitoring the power good supply microprocessor circuit at a safe operating voltage level. Few external components of the KA3501 are required to complete a complete housekeeping circuit power supply for SMPS (Switch Mode Power Supply). The KA3501 is in a 14-pin DIP.
