NCV2820MUTBG

Overview

The NCV2820MUTBG is a mono Class-D audio power amplifier from onsemi, housed in an 8-pin UDFN (2x2.2 mm) package. It operates within a supply voltage range of 2.5 V to 5.5 V and delivers up to 2.19 W RMS output power into a 4.0 Ω load with less than 10% THD+N at 5.0 V. The device features a typical quiescent current of 2.61 mA and ultra-fast turn-on time of 1.0 ms. It includes AEC-Q100 qualification for automotive applications.

Feature Summary

• Filterless Class-D architecture eliminates the need for external output filters when used with inductive transducers.
• Fully differential input design removes the requirement for input coupling capacitors.
• Integrated pop-and-click noise protection circuitry ensures silent startup and shutdown transitions.
• High efficiency operation exceeding 87% reduces battery consumption and junction temperature.

Applications

• Cellular handsets
• Portable electronic devices
• PDAs and smartphones
• Portable computers

Procurement Notes

Verify that the ordering suffix 'MU' corresponds to the UDFN8 package and 'BG' indicates lead-free status. Confirm the 'NCV' prefix meets specific automotive site and control change requirements. Ensure the component is sourced from authorized channels to guarantee AEC-Q100 qualification integrity.

Selection Notes

Select this component for space-constrained designs requiring high efficiency without output filtering. It is suitable for single-supply applications between 2.5 V and 5.5 V. Consider the UDFN8 package for compact footprints. Verify thermal management needs based on PCB layout and load impedance.

Part Context

This part belongs to the NCP2820 series of filterless Class-D audio amplifiers. It shares functional similarities with the NCP2820FCT1G but differs in packaging and automotive qualification. The NCV prefix specifically denotes compliance with unique automotive manufacturing site and control change protocols.

Replacement Considerations

The NCP2820MUTBG serves as a direct replacement for the standard NCP2820MUTBG in non-automotive contexts. For automotive upgrades, verify if the base NCP2820 variant meets specific PPAP requirements.

FAQ

What is the switching frequency of the NCV2820MUTBG?

The internal switching frequency is typically 240 kHz, with a range of 180 kHz to 300 kHz across operating conditions.

How does the NCV2820MUTBG handle short circuits?

It utilizes a patented current breaker circuit that shuts down the output stage if the current exceeds 1.5 A, protecting against excessive power dissipation.
