LP8860-Q1: How to use the boost function

user3529051
Prodigy 30 points
Part Number: LP8860-Q1
I would like to input 12V and boost it to 27V.
Can it be realized only by register setting?
In the case of 27V
"9.2.2 Low VDD Voltage and Combined Output Mode Application"
Is it all right with the circuit described?
Is it necessary to process FB and QSW as described in "9.2.3 High Output Voltage Application"?

    Hi,

    You can just use the typical boost configuration, such as the circuits in 9.2.2. There's no need to use the circuits in 9.2.3.
    The boost output voltage is adjusted automatically according to the LED string voltage.

    Best regards,
