Part Number: TPS61161A Hello,
The TPS61161A LED controller we added to our circuit for use in our project doesn't work. Do we have to apply PWM to the CTRL pin? It doesn't work with just ON/OFF?
Our screen backlight is a 10-LED, 2-series LED.
Could…
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…
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…
Part Number: TPS61161A Dear Team,
Problem facing: IC is not generating the switching pulse at SW pin even after providing the CTRL pin PWM signal.
Please provide any solution.
Input conditions:
1) CTRL Pin input frequency 20Khz, 80% duty cycle…
Part Number: TPS61161A Hi team, I'd like to know if TPS61161A will work without problems in our conditions. Based on the formula in the datasheet, it appears that 160 mA is the maximum output. Since I plan to use 140mA output, is this a usable calculated…
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.
