Housed in a PDIP7 or SOT223 8 AP SUFFIX YYWWG package, the NCP101X offers everything needed to build a rugged and 1 lowcost power supply, including softstart, frequency jittering, 1 shortcircuit protection, skipcycle, a maximum peak current setpoint x = Current Limit (0, 1, 2, 3, 4) and a Dynamic SelfSupply (no need for an auxiliary winding). y = Oscillator Frequency Unlike other monolithic solutions, the NCP101X is quiet by nature: A (65 kHz), B (100 kHz), C (130 kHz) yy = 06 (65 kHz), 10 (100 kHz), 13 (130 kHz) during nominal load operation, the part switches at one of the available A = Assembly Location frequencies (65 100 130 kHz). When the current setpoint falls WL = Wafer Lot below a given value, e.g. the output power demand diminishes, the IC YY, Y = Year WW, W = Work Week automatically enters the socalled skipcycle mode and provides or G = PbFree Package excellent efficiency at light loads. Because this occurs at typically 1/4 (Note: Microdot may be in either location) of the maximum peak value, no acoustic noise takes place. As a result, standby power is reduced to the minimum without acoustic noise generation. ORDERING INFORMATION Shortcircuit detection takes place when the feedback signal fades See detailed ordering and shipping information in the package dimensions section on page 21 of this data sheet. away, e.g. in true shortcircuit conditions or in broken Optocoupler cases. External disabling is easily done either simply by pulling the feedback pin down or latching it to ground through an inexpensive SCR for complete latchedoff. Finally softstart and frequency jittering further ease the designer task to quickly develop lowcost and robust offline power supplies. For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to consume less than 100 mW at high line. In this mode, a builtin latched overvoltage protection prevents from lethal voltage runaways in case the Optocoupler would brake. These devices are available in economical 8pin dualinline and 4pin SOT223 packages.
