NCP1028P100G Description

Short technical summary and product information.

The NCP1028P100G is an offline switching flyback converter from On Semiconductor that integrates a 700V MOSFET with a typical RDS(on) of 5.8 mΩ. It operates at a fixed frequency of 100 kHz and provides a peak current of 800 mA. The device is designed for isolated flyback topologies and includes fault protection for over-power and short-circuit conditions.

 

This converter achieves a no-load standby power of 85 mW at 265 V ac and delivers an input power of 715 mW at 230 V ac with a 500 mW load. Output power is rated at 25 W typical for 230 V ac operation and 15 W typical for a universal input range of 90-265 V ac. The operating voltage range is 7.2 V to 10 V, and the junction temperature range is 0°C to 125°C.

 

The NCP1028P100G is housed in a 7-lead PDIP package (8-DIP, 0.300", 7.62mm, 7 leads) with through-hole mounting. It supports a maximum duty cycle of 80% and is suitable for low-power offline power supply applications.
