禾润升压

1.防削顶失真功能(防破音, Anti-Clipping Function, ACF)
2.免滤波器数字调制,直接驱动扬声器
3.输出功率 3W (VBAT=3.3V, RL=4Ω, THD+N<1%, 20-20kHz full band)
2.0W (VBAT=3.3V, RL=8Ω, THD+N<1%, 20-20kHz full band)
6.5W (VBAT=4.2V, RL=2Ω, THD+N=10%, f=1kHz)
4.效率:
83% (VBAT = 4.2V, f = 1kHz, Load = 4ohm+22uH, Po = 0.6W)
79% (VBAT = 4.2V, f = 1kHz, Load = 4ohm+22uH, Po = 4W)
5.VBAT供电范围:2.7V至5.5V
6.高效自适应同步升压功能
-延长电池播放时间
-可调节最大限流值,有效防止电池拉死
7.AB/D类可切换
8.保护功能:过流/过热/欠压异常保护功能
9.无铅封装,SSOP10L-PP, QFN3×3-16L
