7.4.8.3 Hybrid Modulation

Hybrid Modulation is designed to minimized power loss without compromising the THD+N performance, and is

optimized for battery-powered applications. With Hybrid modulation enabled, device detects the input signal level

and adjust PWM duty cycle dynamically based on PVDD. Hybrid modulation achieves ultra low idle current and

maintains the same audio performance level as the BD Modulation. In order to minimize the power dissipation,

low switching frequency (For example, Fsw = 384 kHz) with proper LC filter (15 µH + 0.68 µF or 22 µH + 0.68

µF) is recommended.
