The NCP101X series integrates a fixed?frequency current?mode controller and a 700 V MOSFET. Housed in a PDIP?7, PDIP?7 Gull Wing, 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).

Unlike other monolithic solutions, the NCP101X is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65 ? 100 ? 130 kHz). When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so?called skip?cycle mode and provides excellent efficiency at light loads. Because this occurs at typically 1/4 of the maximum peak value, no acoustic noise takes place. As a result, standby power is reduced to the minimum without acoustic noise generation.
