The MP7748S is a Class D Audio Amplifier for driving stereo speakers in single-ended configuration or a mono speaker in bridge-tiedload configuration. It is fully integrated audio amplifier which dramatically reduces solution size by integrating the following: 200mO power MOSFETs Startup / Shutdown pop elimination Short circuit protection circuits The MP7748S is capable of delivering 30W per channel into 4O speaker in single-ended output structure, or delivering 60W into 8O speaker in bridge-tied-load output structure. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiencies. The circuit is based on the MPS’ proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply. MP7748S features programmable VDD shutdown voltage for each channel by controlling the UVP node voltage. The default VDD shutdown (rising threshold) voltage is 8.4V if the UVP pin is NC. The MP7748S is available in TSSOP28- Exposed Package.9.5V to 36V Operation from a Single Supply ±5.5A Peak Current Output Output Power at 30V and 10%THD: - Stereo Single Ended: 2 x 30W into 4? Load, - Bridge Tied Load: 60W into 8?
