NCP10672BD100R2G

The NCP10672BD100R2G is a monolithic offline switching converter from On Semiconductor, designed for low-power AC-DC applications. It integrates a 700V MOSFET and a controller in a single 8-pin SOIC package. The device operates at a fixed frequency of 100kHz and supports multiple topologies including buck, buck-boost, and flyback. Key electrical specifications include a typical RDS(on) of 12 Ohms, peak output current of 780 mA, and maximum output power of 15.5 W at 230 Vac adapter configuration. The operating voltage range is 6.7V to 20V. The converter features dynamic self-supply, eliminating the need for an auxiliary winding, and includes internal soft-start (4 ms) and frequency jittering for improved EMI. Protection features include auto-recovery output short circuit and overvoltage protection, as well as current limiting, overload, and overvoltage fault protection. The device is suitable for applications such as adapters, chargers, and auxiliary power supplies. It is available in an 8-pin SOIC package with a maximum operating junction temperature of 150°C.
