onsemi PMIC - PMIC - AC DC Converters, Offline Switchers - NCP1200AP100G NCP1200AP100G

The NCP1200AP100G is a PWM current-mode controller designed for universal offline AC-DC power supplies, operating at a fixed frequency of 100 kHz. It is available in a PDIP-8 package and features low standby power consumption, making it suitable for applications where energy efficiency is critical. The device eliminates the need for an auxiliary winding by deriving power from the high-voltage rail, simplifying design for battery chargers and other power supply applications. This controller includes several protective features, such as auto-recovery from output short-circuit conditions and internal temperature shutdown. It also supports skip-cycle operation, which enhances efficiency at light loads without generating acoustic noise. The NCP1200AP100G is compatible with direct optocoupler connections and offers a peak current capability of 250 mA. Typical applications include AC-DC adapters for portable devices, offline battery chargers, and auxiliary power supplies for various consumer electronics.
