Introduction

AI Translation

The HT8699 is a stereo audio power amplifier with an integrated BOOST converter. In Class-D mode, the built-in BOOST converter allows the boost voltage to be adjusted via an external resistor. Even when powered by a Li-ion battery, it can continuously deliver 2×5.5W output power at 10% THD+N into a 4Ω load with the voltage boosted to 7V. The HT8699 supports seamless switching between Class-AB and Class-D modes, allowing users to switch to Class-AB audio amplifier mode at any time when troubled by Class-D EMI interference. The HT8699 integrates a filterless digital modulation technology that directly drives speakers while minimizing distortion and noise from the pulse output signal. No output filter network is required, and the minimal external component count saves system space and cost, making it an ideal choice for portable applications. In addition, the HT8699 features a built-in shutdown function that minimizes standby current, along with integrated output overcurrent protection, on-chip over-temperature protection, and power supply undervoltage protection.
