The NCP1238BD65R2G is a fixed-frequency flyback PWM controller designed for AC-DC power supplies. It operates at 65 kHz and supports an input voltage range of 9.5V to 28V. The controller features an isolated output topology and is intended for offline flyback converters.
Key specifications include a maximum duty cycle of 80%, ±1.0A peak drive capability, and a 4.0 ms soft-start time. The oscillator precision is ±7% and peak current limit precision is ±5% over the entire temperature range. Fault protection includes current limiting, overload, over temperature, over voltage, and short circuit.
The device is available in a 7-SOIC or 8-SOIC (7 leads) package for surface mount mounting. It is lead-free and halogen-free as verified by the datasheet.
