Part Number: TPS92075 Other Parts Discussed in Thread: TPS92210 , UCC28811 , LM3444 Dear Texas,
our cutomer ha requested an application in which we need to change on the fly the power of a led string. Is there any way to change from a microprocessor…
Part Number: TPS92075
Hi,
This is my first time working with the TPS92075, so I am not familiar with what issues can arise, etc. I am seeing an interesting issue.
The output current is supposed to be 150mA but I am measuring 171mA. I didn't run…
Part Number: TPS92075 Dear Texas Semiconductor,
I have a request for a led driver of 40W supplied with 230Vac.
The leds are made by a string of 18 leds, each one with 3V of voltage forward. The led current is 0.7 - 0.8A. The led configuration is in…
Hello,
There is no pspice or TINA model for this device. But there is an excel design tool available. It's a pretty forgiving circuit so it would also be very easy to use the EVM for most designs by adjusting a few component values to get the current…
Part Number: TPS92075
Hello,
I just powered on my new 230Vac board that uses TPS92075.
This is schematic:
On output there are 4 LED (series, 3Vx4 = 12V), Rsense is 0.95ohm to reach ~500mA
Main problem is that LED current is ~3mA (Voltage…
Part Number: TPS92075 Hello,
I have to develop a new board.
Requirements are:
Input 230Vac, Triac (or IGBT) dimmable
Output: LED 12V, 500mA
I follow TI PMP6016 eference design where I can see buck solution:
In TPS92075 datasheet and…
Part Number: TPS92075 My circuit requires a power factor (PF) greater than 0.9, so I chose to use the TPS92075.Its architecture is a buck converter.
After referring to the circuit design example, the PF value of my circuit would vary between 0.8 and…
Part Number: TPS92075 I have got yet another question.
Is it possible to alter the application from a constant current to a constant voltage mode? The reason why I'm asking is, we want to use about 138 LEDs in our product: 46 strings with 3 LEDs per…
Hi,
There are no spice models available for this device. However you can use one of the reference designs or EVMs available for it here: www.ti.com/.../toolssoftware
Other Parts Discussed in Thread: TPS92075 , TPS92560 TPS92075 as a simple Boost converter. Looks like all I have to do is not connect the PFC connections, and the chip will work as a Boost converter. Is this correct?
