It is required that the peak current is smaller than the OCP (Over current protection) value which is 7.5 A, there are 3 cases which cause high peak current flow through inductor.
θ = 0.5 (BD Modulation), 0.14 (1 SPW Modulation), 0.14 (Hybrid Modulation)
It is suggested that inductor saturation current Isat, is larger than the amplifier peak current during power-up and play audio.
PVDD (V) | Switching Frequency (kHz) | Minimum Inductance (L) (µH) |
---|---|---|
≤ 12 | 384 | 4.7 |
> 12 | 384 | 10 |
For higher switching frequencies (Fsw), select the inductors with minimum inductance to be 384 kHz / Fsw × L. Same PVDD and switching frequency, larger inductance means smaller idle current for lower power dissipation.
