Typical Application Circuit for NCP1070 High-Voltage Switcher for Low Power Offline SMPS

Typical Application Circuit for NCP1070 High-Voltage Switcher for Low Power Offline SMPS. The NCP107x products integrate a fixed frequency current mode controller with a 700 V MOSFET. Available in a PDIP-7 or SOT-223 package, the NCP107x offer a high level of integration, including soft-start, frequency-jittering, short-circuit protection, skip-cycle, a maximum peak current set point, ramp compensation and a Dynamic Self-Supply
