Part Number: LP5522 I want to use this part as a dump, static current limit. From a reading of the spec, it seems that this is possible if I just tie CTRL high. Is this indeed the case? Please verify
thank you
Part Number: LP5522 Is it legitimate to leave the CTRL input of the LP5522 LED driver floating briefly when the chip is powered on?
I am using a microcontroller to pull the pin down to 0, but this only happens a few seconds after the driver chip is powered…
Part Number: LP5522 Hi,
I have a custom board with the LP5522 being controlled using a microcontroller. The microcontroller is controlling the CTRL input pin and Iset is set using an external resistor. The LED output from the LP5522 is driving a LCD backlight…
Part Number: LP5522 Other Parts Discussed in Thread: LP5560 Hi there,
I am looking for an LED driver which can drive the backlight of my display. The display light has a forward voltage of 2.4V and a current of 1 to 20mA based on how bright I want to…
Hi Frank:
Our application is for driving a LED in opto-isolator. I want to use GPIO to control the LED on/off. After I check the TPS92612, Does it have better performance than LP5522 ?? May I know the leadtime and price for LP5522 and TPS92612??
Hi Antonio,
Sorry for late reply that this week is our national holiday.
What is customer's application and requirements for channel number/output current/power supply and so on. We have LP5562/0, LP5522/3/4 in similar WCSP package.
Price information…
Calum,
What kind of package do you prefer? If an BGA is suitable for your application you could check out LP5524, which has 4 LED outputs 5mA default current and 2 channels for external PWM control. This in uSMD package.
There is also 1 LED output drivers…
