ON Semiconductor NCP1x High-Voltage Switchers integrate a fixed frequency current mode controller with a 700V MOSFET. NCP1x are available in a PDIP-7, SOIC-10 or SOIC-16 package. They offer a high level of integration, including soft-start, frequency-jittering, short-circuit protection, skip-cycle, adjustable peak current set point, ramp compensation and a Dynamic Self-Supply (eliminating the need for an auxiliary winding). Features Built−in 700V MOSFET with RDS(on) of 34W (NCP1060) and 11.4W (NCP1063) Built−in 700V MOSFET with RDS(on) of 4.7W (NCP1076/77)/11W (NCP1072/75)/22W (NCP1070/71) Large Creepage Distance Between High-voltage Pins Current−Mode Fixed Frequency Operation - 60kHz or 100kHz (130kHz on demand) Adjustable Peak Current Fixed Ramp Compensation Direct Feedback Connection for Non-isolated Converter Internal and Adjustable Over Power Protection (OPP) Circuit Skip-Cycle Operation at Low Peak Currents Only Dynamic Self-Supply: No Need for an Auxiliary Winding Internal 1ms or 4ms Soft-Start Auto-Recovery Output Short Circuit Protection with Timer-Based Detection Auto-Recovery Overvoltage Protection with Auxiliary Winding Operation Frequency Jittering for Better EMI Signature, Including Frequency Foldback Mode No Load Input Consumption < 50mW Frequency Foldback to Improve Efficiency at Light Load Internal Temperature Shutdown These are Pb-Free Devices Applications Auxiliary, Standby Isolated and Non-isolated Power Supplies, White Goods, Smart Meter, E-Meter Power Meter SMPS Wide Vin Low Power Industrial SMPS  View Product List |
