【应用】昱盛电子3W免滤波器立体声D类音频功率放大器用于电动牙刷,转换效率高达88%
如今,口腔健康被越来越被广大家庭所重视,小朋友从幼儿园开始就被教育早晚刷牙。一款会唱歌的儿童电动牙刷呵护儿童口腔健康的同时,让小朋友尽享刷牙带来的乐趣,因而更能得到小朋友和广大家长的青睐。而这样一款会唱歌的电动牙刷通常都离不开音频功率放大器将声音的能量进行放大的过程。昱盛电子VA2211是一款高性价比的3W免滤波器立体声D类音频功率放大器,常被应用在电动牙刷。
以下是电动牙刷的参考功能框图:
昱盛电子VA2211应用在电动牙刷有如下优势:
1、工作电压为2.8V~5.5V,可在各种电源量程下工作,适合电动牙刷等电池类供电设备;
2、能够在3Ω负载下5V电源下3Wx2高性能输出功率;
3、转换效率88%,发热量小加上芯片的过热保护电路和短路保护等,以确保设备的可靠性;
4、-70dB PSRR,全差分设计减少射频干扰。
综上所述,昱盛电子VA2211这些功能使其成为电动牙刷的理想选择。
