Part Number: TPS61181A Tool/software: Hi,
We're doing a review of a board we have in production that uses the TPS61181A.
In this revision we want the user to be able to set the LED current via the microcontroller, so we'd like to know what the best…
Part Number: TPS61181A Hi,
We are using the TPS61181A as a WLED driver. We are using the 6 IFB outputs with 8 LEDs on each output.
TPS61181A uses low duty cycles (5% to 25%) and the backlight mode is intermittent (200ms ON and 200ms OFF).
The input…
Part Number: TPS61181A Hi,
After reading chapter 8.3.4, we understood what happens if an LED string goes into open circuit.
However, we didn't understand what happens if a string of LEDs is short-circuited.
Can you explain this in a simple way…
Part Number: TPS61181A Tool/software: Hello,
I would like to confirm the maximum current sinks of TPS61181A.
The data sheet states "Six Current Sinks of 30 mA".
Is it correct to assume that the maximum current that can flow per IFB channel is 30…
Part Number: TPS61181A Hi,
We are finishing a project with the TPS61181A and have some questions about the control of the EN and DCTRL pins.
From the datashet analysis we understand that the two pins have Internall pulldown of 800K (typ) and that…
Part Number: TPS61181A Other Parts Discussed in Thread: TPS61181EVM-259 Hi,
We are finishing a project with the TPS61181A.
When we were going to connect the FAULT signal to the microcontroller, we found that the signal was designed to control the…
Part Number: TPS61181A Hi,
Is there any risk of adding a voltage divider on the Vo pin in order to read the voltage with the microcontroller ?
In the tests we performed we used the values below
We only detected a voltage drop of 80 mV but…
Part Number: TPS61181AEVM-259 Other Parts Discussed in Thread: TPS61181EVM-259 , TPS61181A Hi,
We are doing tests on a TPS61181EVM-259 board from which we have removed the jumpers, so that the IFB pins are not connected to Gnd.
The supply voltage…
Part Number: TPS61181A Other Parts Discussed in Thread: TPS60255 , TPS54201 Hi,
I am using TPS61181A driver for driving 6 LED string in parallel (1 LED in each string) with IF = 20mA in each string and VF = 3.3V.
The input supply voltage is 19V and…
Part Number: TPS61181A Hi all Would you mind if we ask TPS61181A? Please refer to the attachment file, and then could you give us the reply? 20190322_TPS61181A.pdf Kind regards, Hirotaka Matsumoto
