The NCP1377DR2 is a PWM current-mode controller designed for free-running quasi-resonant operation. Manufactured by On Semiconductor, this component is housed in an 8-SOIC package and is suitable for surface mount applications.
Key electrical specifications include an operating voltage range of 7.5V to 18V and a frequency capability of up to 100kHz. The device incorporates fault protection features such as current limiting, over-temperature protection, and over-voltage protection. It also includes a 1.0 ms soft-start feature to minimize startup stress.
This controller is designed for offline switch flyback topologies, providing isolated output. Its features make it suitable for various power supply applications, including AC-DC adapters and auxiliary power supplies.
The NCP1377DR2 is RoHS3 compliant and operates within a temperature range of -40°C to 125°C (TJ).
