NCP1015 Self-Supplied Monolithic Switcher for Low Standby- Power Offline SMPS The NCP1015 integrates a fixed-frequency current-mode controller and a 700 V voltage MOSFET. Housed in a PDIP-7 or http://onsemi.com SOT-223 package, the NCP1015 offers everything needed to build a rugged and low-cost power supply, including soft-start, frequency MARKING jittering, short-circuit protection, skip-cycle, a maximum peak DIAGRAMS current set-point and a Dynamic Self-Supply (no need for an auxiliary winding). Unlike other monolithic solutions, the NCP1015 is quiet by nature: PDIP-7 P1015APyy during nominal load operation, the part switches at one of the available CASE 626A AWL 8 frequencies (65-100 kHz). When the current set-point falls below a AP SUFFIX YYWWG given value, e.g.
