FAN7680-PC power output, monitoring IC
The FAN7680 is a complete regulated output circuit for switching mode secondary side use of power supplies. It provides over voltage protection (OVP), under voltage protection (UVP), fault protected output (FPO), remote on/off (PSON), latch-up, internal delay circuit and power good signal generator to monitor and control switching power supplies system output. As for output control, Power Good Output (PGO) and Fail Safe Output (FPO) are also included. It directly senses the OVP and UVP of all output rails without an external voltage divider. The FAN7680 provides a simple and cost-effective solution with minimal external component count, greatly reducing PCB power board space.
