LPA2164 2.5-6.5 Boost,Class AB/D 5W,6.2V@4Ω,10% 1 -70 X X 2 ESOP16

8W Class- F Audio Amplifier With Boost Convertor Integrated

General Description

The LPA2164 is a 8W, 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 2A switch on current for load. It can provide up to 6.5V stable DC voltage for amplifier so that it can display 5.7W output at 10% THD with a 4Ω load. When it provides 5.0V DC voltage, it can provide 3.4W output at 10% THD with a 4Ω load. The LPA2164 also can work at class-AB mode which make LPA2164 could apply to device with radio receiver. The other character of LPA2164 contact OCP、OTP and high noise suppression for FR signal. The LPA2164 is available in ESOP-16.
