1 / 15 page  Preliminary Datasheet LPA2164A LPA2164A–00 Version 1.0 May.-2013 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 15 6W Class- F Audio Amplifier With Boost Convertor Integrated General Description The LPA2164A is a 6W, class-F audio amplifier with boost convertor integrated. It offers low THD+N, allowing it to achieve high-quality Power Supply sound reproduction. The new filterless architecture allows the device to drive the speaker directly requiring no low-pass output filters, thus to save the system cost and PCB area. With high performance inductor and diode，the boost convertor can offer 3A switch on current for load. It can provide up to 6.0V stable DC voltage for amplifier so that it can display 6W output at 10% THD with a 3Ù load. When it provides 5.0V DC voltage, it can provide 3.1W output at 10% THD with a 4Ù load. The LPA2164A also can work at class-AB mode which make LPA2164A could apply to device with radio receiver. The other character of LPA2164A contact OCP 、 OTP and high noise suppression for FR signal. The LPA2164A is available in SOP-16.
