NCP4328BSNT1G Description

Short technical summary and product information.

The NCP4328BSNT1G is a secondary side controller designed by ON Semiconductor for constant voltage and constant current regulation. It operates from an input voltage range of 2.5V to 36V and draws a supply current of less than 100 mA.

 

The device provides a reference voltage accuracy of ±0.5% at 25°C, enabling precise output regulation. The NCP4328B version includes an indication LED PWM modulated driver for status signaling.

 

It is housed in a surface-mount 6-TSOP (SOT-23-6 Thin, TSOT-23-6) package, suitable for compact power supply designs. The operating temperature range spans -40°C to 125°C, allowing use in industrial and automotive environments.
