Rochester Electronics PMIC - AC DC Converters, Offline Switchers NCP1014AP065G

The NCP1014AP065G is a monolithic offline switcher designed for low standby power applications. It integrates a fixed-frequency current-mode controller with a built-in 700 V MOSFET, making it suitable for constructing cost-effective power supplies. The device operates at selectable frequencies of 65 kHz, 100 kHz, or 130 kHz and features skip-cycle operation, which enhances efficiency at light loads while minimizing acoustic noise. This part includes essential protections such as short-circuit detection and latched overvoltage protection when used with an auxiliary winding. It also offers a soft-start function and frequency jittering to improve electromagnetic interference (EMI) performance. The NCP1014AP065G can deliver a maximum output power of 14 W under dynamic self-supply conditions and up to 19 W when an auxiliary winding is utilized. It is available in both PDIP-7 and SOT-223 packages, making it versatile for various applications, including low power AC/DC adapters and auxiliary power supplies.
