onsemi PMIC - PMIC - AC DC Converters, Offline Switchers - NCP1014AP100 NCP1014AP100

The NCP1014AP100 is a self-supplied monolithic switcher designed for low standby power offline switch-mode power supplies (SMPS). It integrates a fixed-frequency current-mode controller with a built-in 700 V MOSFET, making it suitable for applications requiring a compact and cost-effective power solution. The device operates at selectable frequencies of 100 kHz and features skip-cycle operation, which enhances efficiency at light loads by reducing acoustic noise. This part includes essential protections such as short-circuit detection and latched overvoltage protection when an auxiliary winding is used. It also offers a soft-start feature and frequency jittering to improve electromagnetic interference (EMI) performance. The NCP1014AP100 can deliver a maximum output power of 19 W with an auxiliary winding and 14 W in dynamic self-supply mode, making it versatile for various applications, including low power AC/DC adapters and auxiliary power supplies for consumer electronics. The device is available in a PDIP-7 package, facilitating easy integration into designs.
