NCP4328ASNT1G Description

Short technical summary and product information.

The NCP4328ASNT1G from ON Semiconductor is a secondary side controller designed for Constant Voltage (CV) and Constant Current (CC) regulation in switchmode power supplies (SMPS). It features two OTA amplifiers for precise voltage and current loop control, with a ±0.5% reference voltage accuracy at 25°C.

 

This controller supports an operating input voltage range of 2.5V to 36.0V and has a low supply current of less than 100 uA. The NCP4328ASNT1G provides adjustable output voltage and operates at a switching frequency of 1 kHz with a maximum duty cycle of 12.5%.

 

It is housed in a compact 5-TSOP package, suitable for surface mount applications. The device is RoHS3 compliant, Pb-Free, and Halogen Free, making it suitable for various modern electronic designs.

 

Typical applications include offline adapters for notebooks, game stations, printers, LED lighting, and high-power AC-DC converters for TVs, set-top boxes, and monitors.
