Part Number: TPS61176 Hi,
I want to add a capacitor to each IFB pin of the TPS61176 because flickering occurs in the immunity test. Please let me know if there is a recommended range for capacitor capacity.
Best regards,
Hi
Based on loop measurement results, I think the margin is fine. But bench test is also needed under your working conditions to double confirm if any unstable issue will be found.

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…

Hi team, In mode4, if a 120Hz PWM signal is an input, the output will be lost sometimes. Blue : IFBx Green : Input PWM signal This phenomenon only occurs in mode4. It also occurs when Duty is 10% to 0.5%. It does not occur below 0.5%…
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.

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?
Many th…

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 C24…

Do we have a higher Balance rate solution for this multi-channel BL driver IC? The current typical value of TPS61176 is 1.3%. What is the maximum value of it? Thanks…
