The NCP1399AHDR2G is a half-bridge offline PWM controller designed for AC-DC converter applications. It operates at a fixed 50% duty cycle over a wide frequency range of 20kHz to 750kHz. The device requires an external supply voltage between 9.5V and 20V, with a typical startup threshold of 15.8V.
Key protection features include current limiting, open loop detection, overload, over-temperature, over-voltage, and short circuit protection. The controller uses half-bridge topology with isolated output, and no internal power switches, requiring external MOSFETs.
Packaged in a 16-SOIC surface-mount package with 14 leads, the NCP1399AHDR2G operates over a junction temperature range of -40°C to 125°C. According to the available data, the device is RoHS3 compliant with an MSL of 1 (unlimited).
