The SG6108 controller is designed for desktop PC switching mode power supplies. It provides everything necessary to monitor and control the output of the power supply. Remote ON/OFF control, power good circuitry, over-voltage protection, over-power protection, and over-current protection are all included. The SG6108 directly senses all the output rails for over voltage conditions without requiring external dividers. An innovative AC-signal sampling circuit provides an adequate power-down warning signal for PG. A built-in timer generates accurate timing for the control circuit. Cycle-by-cycle PWM switching protects the power transformer from saturation and ensures a rapid response for short-circuit protection. This greatly reduces the stress on the power transistors. The SG6108 utilizes a minimum number of external components while including all the functions needed for push-pull and/or half-bridge topologies. This decreases production costs and PCB space while increasing the power supply's MTBF. |
