NB671GQ-Synchronous rectification and buck module solution

Overview

Chip solution DC-DC chip NB671GQ

Modular PCB

Input voltage: 7-22v (12V recommended)

Output voltage: 0.604v-5.5v (default setting 5v)

Output current: Test 3A (maximum 6A, large current requires sufficient heat dissipation)

Switching frequency: 500 kHz switching frequency

The NB671 is a fully integrated high-frequency synchronous rectification step-down switch mode converter.

It provides a very compact solution up to 6A continuous output current and 9A peak current over a wide input voltage range with excellent load and line regulation.

NB671 operates with high efficiency over a wide output current load range.
