Typical Application for NCP1013 a Typical Converter Delivering 7W from a Universal Mains. The NCP101X series integrates a fixed-frequency current-mode controller and a 700 V MOSFET. Housed in a PDIP-7 or SOT-223 package, the NCP101X offers everything needed to build a rugged and low-cost power supply, including soft-start, frequency jittering, short-circuit protection, skip-cycle, a maximum peak current setpoint and a Dynamic Self-Supply (no need for an auxiliary winding)
