Other Parts Discussed in Thread: LP8556 Hello,
I would like to use the LP8556 with 6 LED strings, but with only one string on at a time (could be any of the 6). Can I do this by setting PS_MODE to '000' then adjust LED_EN according to which string I…
Other Parts Discussed in Thread: LP8556 Hi Team, It seems LP8556 has overcurrent protection, however I think there is unavoidable current path (the red arrow) when VOUT or LED string is shorted to GND. Do you recommend electrical fuse if my customer concerns…
Hi-
I'm sorry for the delay.
A new device option pre-programmed for 50mA/CH support requires involvement of a development team. I suggest contacting your sales representative who can request a new device option.
Regards,

Other Parts Discussed in Thread: LP8556 Hi Team, I believe LP8556 doesn't have I2C clock stretching function. Is my understanding correct? I would like to confirm just in case. Best Regards, Yaita / Japan disty
Hi Team, The datasheet shows "Recommended Inductance for the Boost Power Stage" as the following. If my customer's application is the following, can I recommend the inductor of red part above? ---------------------------------------------------- Number…
Other Parts Discussed in Thread: LP8556 , LP8555 Hi,
My customer has questions about LP8556. Could you tell me about questoins?
[Question] My customer consider to use LP8556 under the following condition.
Vin=3.3V Vout=38.5V 11S6P Iled=20mA/ch Dimming…
Other Parts Discussed in Thread: LP8556 I don't know how to set LP8556 BOOST TO 22V AND CUREET to 20mA VIA I2C ，can you tell me which regester need to write ，and the detailed value ？
Part Number: LP8556 Hi Team, My customer considers to use LP8556 in his system and has the following question. Is it possible to apply 1.8V to SCL and SDA through pull-up resistor when EN/VDDIO=Low (0V)? *According to datasheet, EN/VDDIO is power supply…
Part Number: LP8556 I've got an application that uses a 22.8Vf string of white LEDs at 70mA nominal each. I'm wondering if it's possible to parallel two channels at a time to make the LP8556 a 3-channel product but capable of my needed 210mA total current…
Part Number: LP8556 Hi Team, The PWM output of LP8556 can be controlled by both the PWM input duty cycle and the Brightness register by setting BRT_MODE=01b or 11b. Is there any advantage to use both PWM input duty cycle and the Brightness register? My…
