Part Number: TPS61081 Hi, everyone:
I test my backlight circuit base on TPS61081. It do not work since I do some welding on it. Maybe it has been broken due to short circuit caused by the soldering tin.
I clean it and take a picture by X-Ray:
…
Other Parts Discussed in Thread: TPS61081 , TPS61088 What is the max. current supply output for this part? Its not clear from the datasheet. The part is listed on Digikey as follows:
Current - Output 1.3A (Switch)
The part has been designed to provide…

Thnak you for quickly answer. Our customer has not yet decided specification. Although I was recommend TPS61085 to the customer, but they said that when a device was a disable, the input current does not leak to output is good. I asks to a…
Other Parts Discussed in Thread: TPS61081 Hello. I built DC/DC converter based on TPS61081.
The input voltage is about 3.5V. Output divider is calculated for 5V output.
In fact I have unregulated output voltage about 9V & it depends on input voltage…
Other Parts Discussed in Thread: TPS61081 We are using the TPS61081 to drive the backlight of a TFT display using the circuit shown on page 24 of the datasheet. We have noticed that the TPS61081 does not behave as expected with higher frequency PWM, and…

Other Parts Discussed in Thread: TPS61081 hello,
i have some questions about the TPS61081 and specially the figure 24 on the datasheet.
1)- i want to know first the VFb voltage of the chip ?is it 1.1229V or 0.2V ?
2)- if it is 1.1229V as mentioned…
Other Parts Discussed in Thread: TPS61081 Hello,
Customer is using the TPS61081 for LED backlight control, using Fig 24 in the datasheet. They would like to know if there is a recommended FET for the PWM dimming?
Thanks in advance,
Mohammed
Other Parts Discussed in Thread: TPS61081 Dear All,
In AM335X sitara starter kit backlight IC TPS61081 is designed in such a way that to provide 32mA @ 20V. We would like to know how to change output current and voltage setting. In TPS61081 datasheet…
Other Parts Discussed in Thread: TPS61081 , TINA-TI Hi!!.. I need to simulate a circuit using the TPS61081 chip. Where can I download a library containing this model in order to use it in the software TINA-TI.????
THANKS..
