Abstract:
1. A single-ended primary-inductance converter (SEPIC) controller configured for operation as a SEPIC power converter with an LC network including a transformer with a primary side coil and a secondary side coil, the LC network further including a primary side inductor, a primary side capacitor, and a primary side current limiting component, the SEPIC power converter operable to convert power from an input power source into a regulated output power supplied to a load, the SEPIC controller comprising: a transistor switch configured to couple between a switch node and a system return; the transformer configurable with a first end of the primary side coil coupled to the switch node; the LC network configurable with a controller configured to control the transistor to selectively connect the switch node to the system return, and thereby control current through the primary side coil to supply the regulated output power from the secondary side coil.
