LP8866-Q1: Phase Shift PWM in Hybrid dimming

Masatoshi Oguri

Part Number: LP8866-Q1

Hello,

In Hybrid mode, is the PMW phase shifted? Or phase shift is active only in Phase-shift PWM mode?

Thank you.

Hi Oguri-san,

Hybrid dimming and phase shift are different features, although they might both improve the efficiency.

phase shift is only enabled in phase shift mode.

Hi Gracie,

It seems my customer sees phase shift in Hybrid Mode. Would you please doublecheck if it is true?

Thank you.

Hi, Oguri-san

Pls see the dimming block in below.

Hybrid dimming will still go through the phase shift block, so it will has phase shift function.

Only direct PWM dimming will not go through that block.
