LM48510 Boosted Class D Audio Power Amplifier
General Description
The LM48510 integrates a boost converter with a high efficiency mono, Class D audio power amplifier to provide 1.2W continuous power into an 8 speaker when operating on a 3.3V power supply with boost voltage (PV1) of 5.0V.
When operating on a 3.3V power supply, the LM48510 is capable of driving a 4 speaker load at a continuous average output of 1.7W with less than 1% THD+N. The Class D amplifier is a low noise, filterless PWM architecture that eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design. The LM48510's switching regulator is a current-mode boost converter operating at a fixed frequency of 0.6MHz. The LM48510 is designed for use in mobile phones and other portable communication devices. The high (76%) efficiency extends battery life when compared to Boosted Class AB amplifiers. The L
