S3526 Overview
UTC S3526 is used for switching power supply system. UTC S3526 provides protection functions, over-voltage protection, over-current protection, under-voltage protection and power good signal generating. OVP/UVP (Over-Voltage/Under-Voltage Protection) monitors triple 12V to protect our power supply and PC, FPO goes to high when one of these supply voltages exceeds their normal operation voltage range.
