Part Number: TPS61160A Tool/software: Hi support team,
When dimming while changing the PWM duty ratio, the anode voltage fluctuates as shown below.
Brightness [％ ]
Anode Voltage [ V]
Cathode Voltage [ V]

Part Number: TPS61160A Tool/software: Hi Team,
Would it be okay to set Rset to 2.5Ω and use the CTRL-pin to adjust the LED current from 0 to 80mA?
All of efficiency vs output current graphs(Figure 1 to 4) in the data sheet are up to 50mA, so the…
Part Number: TPS61160A Hi,
Can I use a TPS61160A as shown below, with Vin=3V3 and the inductor connected to a battery (3.4 to 12V)
I think it should be more efficient when the output is a low current (which mine in), because the Iq will come from…
Part Number: TPS61160A Other Parts Discussed in Thread: TPS61160 , TPS92380 I want to use TPS61160A IC for my Backlight in the touch panel.
My input voltage is 12V and I want 75mA output current and 21V output voltage so that I can achieve full brightness…
Part Number: TPS61160A On 5.3Vin → 12Vout / 20mA condition for TPS61160A, L: 20μH and Cout: 10μF become unstable and L: 10μH and Cout: 1μF become stable.
Please let me know about two points below;
①is there calculation method for internal loop compensation…
Part Number: TPS61160A Other Parts Discussed in Thread: LM2733 Hi team,
My customer want to use TPS61160A as voltage regular boost as below(as they need constant voltage to drive load rather than constant current):
Could you help to confrim if this…
Part Number: TPS61160A Dear team,
Why is different switching waveform (low state) by difference input voltage of TPS61160A? Is it no problem?
IN=7V, OUT=19.9V
IN=5V, OUT=19.9V

Hi there,
I'm trying to power my TFT LCD display, which is rated at 500cd/m2 luminance rating. The only issue being that the screen clearly does not look as bright as it should be, which makes me think something is up with the…
Hi Lucas,
According to your application, your maximum current is 800mA which is above over the current limit of TPS61160A. So this device may not suitable for you. Thanks.
