Part Number: TPS61176 Hi team, Is it possible to set a duty 1% at 100Hz? If it was inputting a low-frequency signal(100Hz), could you tell me if you have anything to worry about? Sincerely. Kengo.
Part Number: TPS61176 In the previous revision of our design we did not have the protection (PMOS) circuit and the MODE/FAULT pin was simply pulled to GND through a 1.3M resistor. In that original version the part behaved as expected.
The PWM signal…
Part Number: TPS61176 Other Parts Discussed in Thread: LP8553 , LP8556 Dear team
The customer would like to select the solution of LED driver.
The spec as below
Vin:2.8V~4.5V
ILED=40mA/per channel
VLED=30V/4ch
Could TPS61176 support this spec…
Hi Sir,
No, the maximum current ability for each current sink is 35mA, please not exceed this spec and we only guarantee that we can deliver 35mA per channel. Thanks.

Dear Sir
we have implement Below Schematic and it is not generate Output of 28v but it generate only 4v.
right now we have tied En Pin with Vin pin. voltage input is 4.0v.we have use 10uf capacitor instead 4.7uf capacitor on…
Part Number: TPS61176 Other Parts Discussed in Thread: TPS61169 Hi. Expert.
My customer is using TPS61178RTE as WLED backlight.
What is the maximum sink current of each LED channel?
He set it to 80mA per channel, is that possible?
He requested…
Part Number: TPS61176 For TPS61176 chip, the current EN pin voltage we use is about 1.7V (as shown in the red box below). Under this condition, when the output channel is > = 3 (the total output current is about 60mA), the problem of backlight flash caused…
Part Number: TPS61176 Hi,
I used TPS61176 for 8S6P LED,
Lithium battery power
LED 3.3V 15mA
Now I'm trying to figure out whether the schottky value is going to be 1A or 2A,can you help me?
Part Number: TPS61176 Hi,
We are using TPS61176 to drive our WLED.
Our observation is that, when
1. VIN = 3.3 V, Current consumed to drive our LEDs = 50mA
2. Now if we reduce VIN to VIN= 3.2 V, Current consumed to drive our LEDs = 2 A
3. Now…
Part Number: TPS61176 Hello team,
I have a quick question about TPS61176 use case. Is it acceptable if a user doesn't use the boost converter? (e.g. both 5V for Vin and 24V for LEDs can be provided)
Thanks in advance. Shinya Sawamoto TI Japan East…
