Part Number: TPS61161A Tool/software:
We're following the provided schematics, but even with an Rset resistance of 1.2 Ohms (grounded to FB), we're still not achieving sufficient voltage/current to activate the backlight. Our backlight specifications…
Hi,
Happy to hear the problem is solved, I'll close this thread now. If you have other questions, please reply to this thread and it will re-open again.

Hi Kengo,
Based on the measurement, Iout=140mA is permitted. And when the inductor is lowed to 36uH, the theoretical max Iout=148mA.

Part Number: TPS61161A I am using TPS61161A for 100mA, 24V output.
100mA output current is limited by Rset on FB pin to 2 Ohm.
Cout and Lout are calculated to 1uF and 18uH respectively.
12V input is available at Vin
We are facing internal Mosfet damaging…
Part Number: TPS61161A Hello guys,
One of my customers is considering using TPS61161A for their new products. They have the following question at this moment. Could you please give me your reply?
Q. Can a different voltage from VIN terminal one be connected…
Part Number: TPS61161A Hi,
Customer would like to use TPS61161A as voltage regulator.
Voltage regulation is normal but under 0.1A load, voltage is decreased.
Could you check this and review the schematic for 0.5A load with 5V?
Thanks.

Part Number: TPS61161A Can you please help me to check what is the max current with our usage, the detailed digit as below listed.
input voltage range = 3.2V-4.2V, Li-ion battery supplied voltage
output voltage range = 5~7V, 2 series LED, with 3.0V nominal…
Part Number: TPS61161A Other Parts Discussed in Thread: TPS61160A Dear sir,
For TPS61160A, which is having Vref Min=196mV and Max=204mV
Can I say each IC will fix to one voltage level (eg 197mV) only during operation from time to time and It will not…
