Part Number: TPS61500 Tool/software: Hello Support Team,
I am designing a backlight driver circuit using the TPS61500 and have selected a switching frequency of 1.2 MHz to minimize the power stage components and reduce the physical size of the design…
Part Number: TPS61500 Tool/software: Hi,
We use the TPS61500 for the LED drvie, the input voltage is 5V and the output voltage is 26V, the PWM frequecy is 40KHz, 3.3V, the duty is 57.5, the design is OK;
Now, we change the input voltage to 10.4V,…
Part Number: TPS61500 Other Parts Discussed in Thread: TPS61169 , , TPS92360 We have a 3V (700mA) LED, which needs to be modulated from 100Hz to 2MHz with a 50% duty cycle (square wave). I wannted to enquir if the above driver (TPS61500) will work. Also…
Part Number: TPS61500 Tool/software: Hi champs,
My customer has been using TPS61500 in PWM dimming mode with a PWM from MCU connected to EN pin.
In the new design, they are considering to cancel the MCU, and they do not need any dimming. Can they…
Part Number: TPS61500 Tool/software: We are looking for an LED driver with the following specification: Vin 3 to 12, better 20V. Vled 22V with 100 mA current. The backlight should be controlled via PWM. The decisive criterion is a low duty cycle so that…
Part Number: TPS61500 Tool/software: I am currently checking if the TPS61500 is compatible for our use-case where we want to drive a backlight which needs 24V and shall draw 400mA total. (4 strings of 8 series LED's)
The input for the TPS61500 shall…
Part Number: TPS61500 Tool/software: Hii Team,
We are Integrating OPT 3004 Light Sensor from TI with TPS 61500 LED Driver IC for Night Vision Camera, Based out the Light Intensity, Can we change the current through LED Dynamically ?
Regards, …
Part Number: TPS61500 Tool/software: I am in the process of reviewing an LED current driver design which uses the Pure PWM dimming method for the TPS61500.
On page 13 of the specification, it explicitly states: "Floating the DIMC pin, an external PWM…
Part Number: TPS61500 Hi,
I have a question about the TPS61500. Can be used in common with several types of LCDs with the same screen size. We are considering an LCD backlight circuit.
Some types of LCDs require a constant voltage supply of 5V or…
Part Number: TPS61500 Tool/software: Hii Team,
We have Implemented TPS61500 in a Dot PCB, we have observed that the IC is boosting the input voltage. The Design Parameters are
Input Voltage : 3.3 V
Inductor Value : 34 uH
Required Output Voltage…
