Introduction

AI Translation

The NCP101X series integrates a fixed-frequency current-mode controller with a 700 V MOSFET. Available in PDIP-7 or SOT-223 packages, it provides everything needed to build robust, low-cost power supplies, including soft-start, frequency jitter, short-circuit protection, skip-cycle operation, maximum peak current setpoint, and Dynamic Self-Supply (no auxiliary winding required). Unlike other monolithic solutions, the NCP101X operates inherently quietly: during nominal load operation, the device switches at one of the available frequencies (65, 100, or 130 kHz). When the current setpoint falls below a given value (e.g., reduced output power demand), the IC automatically enters the so-called skip-cycle mode, delivering excellent efficiency at light loads. Since this typically occurs at one-quarter of the maximum peak, no acoustic noise is generated. The result is minimized standby power without acoustic noise. Short-circuit detection activates when the feedback signal disappears — for example, under a true short-circuit condition or in the event of optocoupler failure. External disable is easily implemented by simply pulling the feedback pin low or latching it to ground via an inexpensive SCR. Finally, soft-start and frequency jitter further ease the designer's task of rapidly developing low-cost, robust off-line power supplies. To improve standby performance, connecting an auxiliary winding disables DSS operation and helps achieve power consumption below 100 mW at high line voltages. In this mode, the built-in latching overvoltage protection prevents a catastrophic voltage runaway in the event of optocoupler failure. These devices are offered in cost-effective 8-pin DIP and 4-pin SOT-223 packages.
