NB670AGQ-P

Overview

The NB670AGQ-P is a synchronous step-down converter with an integrated low-dropout regulator, manufactured by Monolithic Power Systems. It operates within an input voltage range of 5 V to 24 V and delivers up to 6 A on its primary output. The device features a fixed 3.3 V secondary LDO output. It utilizes a constant-on-time control architecture with a switching frequency of 500 kHz. The component is housed in a QFN-16 package and supports operation across a temperature range of -40 °C to +125 °C.

Feature Summary

• Integrates a high-current synchronous buck converter alongside a dedicated 3.3 V LDO for auxiliary power generation.

Applications

• Power distribution units requiring simultaneous high-current and low-noise rail generation

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Ensure the selected variant matches the required input voltage range and output current specifications for the target application design.

Selection Notes

Select this component when a single IC solution is needed to provide both a high-current adjustable or fixed output and a separate regulated 3.3 V supply. Compare against the NB670GQ-Z if only a single buck output is required, or consider the NB671 series for adjustable buck outputs without the integrated LDO feature.

Part Context

This part belongs to the NB670 family of power management integrated circuits from Monolithic Power Systems. These devices are designed for applications requiring efficient power conversion in compact form factors. The family includes variants with different output configurations, such as single-output buck converters or those with additional linear regulators.
