General Description

HT81293, integrated with a boost converter, is a mono Class D audio amplifier that drives up to continuous 18W (10% THD+N, 1kHz) into 4ohm speaker from a Li-battery voltage.

HT81293A integrates an adaptive boost converter that generates a Class D amplifier supply rail tracking the audio signal, which will significantly improve the efficiency and extends the playing time in battery supply applications.

The output voltage of boost converter in HT81293F is forced into 9V or 12V and it provides to the class D amplifier.
