Part Number: TPS61169 Hi,
TPS61169 only have 1 output channel. Here’s the case: our backlight LED have two strings, and there’s 8 LED on each string. If we connect both of this two strings on this 1 output channel of TPS61169. Considering that the working…
Part Number: TPS92360 Other Parts Discussed in Thread: TPS61169 , The datasheet of TPS92360 is highly similar to TPS61169. Not just the pin function, also the details numbers in the specification and circuit.
Are TPS92360 can act as a direct replacement…
Part Number: TPS61169 Other Parts Discussed in Thread: TPS61170 Hi,
I am designing a IR LED driver using TPS61169.
The design requirements are follows:
Vin(max)= 5V
Vout(max)= 13V
Iout(max)= 100mA
As per my calculation I selected 10uH inductor. for the…
Part Number: TPS61169 Dear TI Team
I would like to confirm the output current regulation of TPS61169. The TPS61169 web page states that the Current per LED value is 400mA, but the electrical characteristics of the data sheet do not have a parameter that…
Part Number: TPS61169 Hi Team,
We are planning to use TPS61169 as a IR LED driver in our design. The requirement are as follows,
Input voltage : 5V
Output voltage : 18.6V
Output Current : 100mA
In datasheet, Its shown that the inductor value is 4.7…
Part Number: TPS61169 Hi, Support Team
A customer is designing an e-book.
I want to operate the Back-light LED using the following products,
As a result of checking, it seems that the number of strings is recommended as 10.
The customer's spec is…
Part Number: TPS61169 HI team,
I need confirmation on the Control Pin of the driver IC.
I have a processor whose output levels are 1.8V , which is connected to control pin of the driver.
Will this 1.8V levels will be sufficient for the proper operation…
Part Number: TPS61169 Hi team,
Can you have look at the following customer inquiry please?
In a current project I used the TI TPS61169 to drive a display backlight. The driver worked without problems in the pre-series, but currently we are struggling…
Part Number: TPS61169 There are another 11 LEDs in series (12 toral - set to 50mA max wire 3R9)
The LIGHTS net is direct from a 1.8V CPU, and voltage goes rail to rail (checked on scope). When we run the PWM at around 500Hz (way below the spec) , the…
Part Number: TPS61169 Dear Sir/Madam,
My customer wants to connect one MCU output port to two TPS61169 CTRL pin to control two TPS61169 at the same time. Please refer to the attached file.
As far as I know, this relates to CTRL pin sink current and MCU…
