PRODUCTION DATA
The LP8868 family has four optional dimming modes determined by the waveform in PWM and ADIM pins. The dimming mode is started either 1 ms after VIN exits UVLO or 300 μs after renable by EN/PWM pin. The configuration to one of the four dimming modes are shown as below.
Dimming Mode | EN/PWM Pin | ADIM/HD Pin |
---|---|---|
PWM Dimming | PWM signal | High |
Analog Dimming | High | PWM signal |
Hybrid Dimming | PWM signal | Low |
Flexible Dimming | PWM signal | PWM signal |
