Part Number: TPS61160 Hi, we are trying to use TPS61160 into our product. It was controlled by linux with PWM driver settings. However, at one particular PWM settings, the display becomes flickering. Below is the PWM signals and schematic, could you give…
hi Hao
Sorry for late reply due to business trip.
Then maybe you can go with your current solution by " Watchdog every 8 seconds after reset ". Honestly speaking, I cannot think of what difference this will cause to the LED driver, this action…
Part Number: TPS61160 Other Parts Discussed in Thread: TPS61161 , TPS92391 Hi Team,
Could you check the max operation current for TPS61160?
Many Thanks,
Jimmy
Part Number: TPS61160 Other Parts Discussed in Thread: TPS61161 , TPS92360 , , TPS61165 We are using this chip to drive the LED backlight for a TFT display. Initial prototypes worked extremely well, but we have just finished a 40 piece production run where…
Part Number: TPS61160 Hi,
The customer is using TPS61160 for LCD backlight.
When dimming is performed by changing the PWM, the LED_A outputs a voltage of 7.6 to 8.6V, but the LED brightness does not change.
Please raise the output of LED_A to 10V without…
Part Number: TPS61160 Other Parts Discussed in Thread: TLC59108 Hi All,
We have a LCD with 6 parallel LEDs, in "common Anode" format as shown below. Backlight LED voltage Vf= 3.3V maximum. LED current If = 120mA. Please let us know if TPS61160…
Part Number: TPS61160 Hi team,
Please see 8.2.3 Li-Ion Driver for 6 White LEDs in datasheet. Input voltage is 3V to 5V. Inductance is 10uH. Io=20mA. Vo=19V.
According to the calculating results in following picture, the ripple current of inductor is 0…
Part Number: TPS61160 Hi,
I have a question about TPS61160 LED driver. Condition is below.
- 4 LED: Not white LED, typ.1.6V Vf / 1 LED - CTRL: connect to 3.0V_REG - LED current: about 2 - 40 mA (typ. about 15mA)
In the datasheet, "Maximum duty cycle" is…
Part Number: TPS61160
This circuit is used to drive a 4-LED Series LCD backlight, but there will be a burst of flicker and a burst of normal. Measure the PWM waveform, and it is found that the duty cycle will change when flashing. The welding problem…
