NCP2830

1W Constant Filterless

Class-D Audio Amplifier

NCP2830 is a cost effective mono audio power amplifier designed

for portable communication device applications such as mobile

phones. Due to its integrated charge pump structure, this part is

capable of delivering 1 W of continuous average power to an 8.0 W

Bridge Tied Load no matter the voltage provided by a lithium/Ion

battery.

MARKING

DIAGRAM

NCP2830 is a preferred solution for long playback audio with

minimum space required.

Added to a fast start−up time of 200 ms and a −88dB PSRR, the

NCP2830 audio power amplifier is specifically designed to provide

high quality and level output power from low supply voltage,

requiring very few external components.
