LP8866-Q1: LP8866-Q1的Phase-shift PWM Mode调光模式下调光频率与调光占空比由谁决定

Hi, 

In phase shift mode, the frequency is only related with the FSET resistor. Input frequency has no influence for PWM dimming frequency.

输出电流调节是不是默认由28PIN PWM输入的PWM占空比决定？此时对28PIN PWM输入的PWM频率有要求吗？

HI, Ansel

Pls refer to the datasheet spec. Analog dimming mode will change the duty into the current value.

Phase-shift PWM Mode调光模式不是PWM调光吗？怎么会和Analog dimming mode 有关系呢？

Hi, Ansel

For  PWM dimming mode, duty will change the output duty.

For Analog dimming mode, duty will change the output current. It depends on which mode you use.

If you want to change the current in PWM dimming, pls consider the current register.
