Herun Booster

1. Anti Clipping Function (ACF)
2. Filter free digital modulation, Direct drive speaker
3. Output power 3W (VBAT=3.3V, RL=4 Ω, THD+N<1%, 20-20kHz full band)
2.0W (VBAT=3.3V, RL=8 Ω, THD+N<1%, 20-20kHz full band)
6.5W (VBAT=4.2V, RL=2 Ω, THD+N=10%, f=1kHz) • Efficiency:
83% (VBAT=4.2V, f=1kHz, Load=4ohm+22uH, Po=0.6W)
