15W 5.0V high-efficiency USB adapter reference design board, using Infineon's quasi-resonant PWM IC ICE2QS03G with CoolMOS™ IPS65R1K0CE (IPAK) and secondary side synchronous rectification IC with OptiMOS™ BSC067N06LS3 G (ThinPAK), small size, high efficiency, Various protection modes can be provided for high-reliability systems.
Today's smartphone/phablet/tablet designs require high-quality music and audio playback with low power consumption.
In recent years, the development of wireless technology has gradually matured into an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless speakers are one of them. In addition, the increasing development of wireless transmission technology has also led to the wirelessization of music peripheral products. This is a technological breakthrough, which also allows this type of product to have more imagination in the design, and also makes the fun of enjoying music more seamless. burden.
This is a 100w stereo amplifier board. This project can easily play two 50w speakers.
A reference solution for a DSC/DVC device with low-power features, high-quality codecs, and integrated input/output interfaces such as microphones, speakers, headphones, and stereo lines. Using the advanced signal processing function of the Nuvoton stereo codec series NAU8822L chip can reduce noise signals and enhance audio quality.
The smart player integrates multimedia playback, network interconnection, human-computer interaction and other applications. As a co-processor, Nuvoton microcontroller's main functions are power control, audio and video link switching, human-computer interaction and function module control.
