NS6322 Integrated Circuit by NSIWAY | SOP-8 Package

NS6322 | Synchronous Step-Down Power Supply IC
Package: SOP-8 | Pins: 8 | Output Current: 2.4A

The NS6322 is a high-performance synchronous step-down (buck) power supply IC designed to support wide input voltages from 4V to 30V. Delivering a continuous output current of up to 2.4A, it provides excellent constant voltage (CV) and constant current (CC) regulation with ±5% accuracy, making it an ideal solution for battery charging and power management applications.

Operating at a fixed switching frequency of 130kHz, the NS6322 achieves high efficiency (up to 92%) while ensuring good EMI performance. It uses a current-mode loop control principle, enabling fast dynamic response without requiring external compensation components, which simplifies circuit design.
