Part Number: LP8873-Q1 Hello TI team :
Application for our design LP8873 , combined all channle to one string with 8*LED current 230mA ,boost overvoltage limit is 35V , currently we are testing the LED- short to GND detetion function , get the result…
Part Number: LP8873-Q1 hello Experts:
my use case : Voutmax=12*3.1=37.2V Iled=0.118mA/per channel*4=0.472mA
according to the equation from datasheet:
K L =0.5 fsw=400kHz
L=4*(37.2+0.5)/(27*0.472*0.5*400*1000)=59uH
Regarding inductor selection…
Part Number: LP8873-Q1 Dear TI,
I am looking for an automotive LED driver with Phase shift PWM. One of the components I came across was the LP8873-Q1. The price and relative simplicity (based on the amount of pins) has me interested. However, there…
