Part Number: LP8543 Other Parts Discussed in Thread: OPT3001 Hello
I'm using LP8543 in my project. I'm using OPT3001DNPR ambient light sensor for this. I wanted to get clear idea about these two device interface. How can I connect ALSO and ALSI pins…
Part Number: LP8543 Other Parts Discussed in Thread: TPS61177A , LP8556 , TPS61187 , TPS61196 , TPS61199 Hello
I'm using LP8543 in my project. For this IC I will provide PWM and EN. I'm not going to use any ALS sensor. As per datasheet recommendation…
Part Number: LP8543 We are using this driver in stand alone mode to drive sharp LS037V7DW05 display backlight. Device is rated at 60C and we are seeing intermittent backlight shutdowns at 60C with Driver reporting overcurrent condition.
Usually problem…
Other Parts Discussed in Thread: LP8543 I have some trouble configuring the LP8543. I have a backlight with 4 strings. The strings are connected to OUT1 - OUT4, OUT5 - OUT7 are left unconnected. When I set the PWM signal to high, the backlight turns on…
Other Parts Discussed in Thread: LP8543 Does the LP8543 LED Driver Thermal Pad need to be connected?
Can it be connected to GND in a circuit for better heat sinking?
Thanks
Other Parts Discussed in Thread: LP8543 Hi,
I was wondering if someone could point me to an example initialization of the LP8543 LED chip. I would like to incorporate this part in an embedded system running linux, but have not been able to locate a…
Other Parts Discussed in Thread: LP8543 Hi,
The LP8543 datasheet makes reference to EEPROM register 0x29 when adaptive mode is enabled as a default. This EEPROM register offset does not appear in the datasheet's Table 15 "LP8543 EEPROM Memory Map".…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
