NCP1399AIDR2G Description

Short technical summary and product information.

The NCP1399AIDR2G is a half-bridge offline switching controller from On Semiconductor, designed for AC-DC converter applications. It operates over a frequency range of 20 kHz to 750 kHz and a supply voltage of 9.5 V to 20 V. The controller features a 50% nominal duty cycle and provides isolated output, making it suitable for isolated power supply designs.

 

The device includes comprehensive fault protection features such as current limiting, open loop protection, overload protection, over temperature protection, over voltage protection, and short circuit protection. This ensures robust operation in demanding environments. The operating temperature range is -40°C to 125°C (junction temperature), allowing use in industrial and automotive applications.

 

The NCP1399AIDR2G is housed in a 16-SOIC surface mount package (0.154 inch width, 3.90 mm width) with 14 leads. The supplier device package is 16-SOIC. It is listed as RoHS3 compliant, MSL 1 (unlimited), and REACH unaffected.
