Part Number: TPS92512 Hi all!
I'm new to the forum, so I hope everything I'm posting is correct :-)
I'm using a TPS92512 to drive a led channel made by 6 Cool White led ( CREE XP-G2 ); this is the schematic: so all ok, it works and I'm able…
Part Number: TPS92512 Other Parts Discussed in Thread: TPS61500 Hi, My customers are looking for LEDdriver. Customer requirement is -Vin=3.5V to 7V -Vout=12V -Iout=0.7A Please tell me the products that meet the above specifications. I found TPS92512 from TI web…
Part Number: TPS92512 Other Parts Discussed in Thread: TPS92515 , LM3404 , LM3406 , LM3409 I am using TPS92512 to drive one LED. The input voltage is 5V, the output is 3V. inductor is 47uH, output capacitor is 4.7uF. Pdim is used to control intensity. 1K…
Other Parts Discussed in Thread: TPS92512 , TPS92515 , LM3409 However. I want to be able to run in a sort of bypass mode at times as well I would assume PWM=100%
At this duty cycle with 5V in, what might the voltage dropout be? I need the dropout as low…
Other Parts Discussed in Thread: TPS92512 , TPS92515 Hi,
I'm having trouble getting TPS92512 evm board to regulate current fast enough. After the cirquit has setteled(PWM low) for 1-2 seconds, the time for output current to reach the setpoint takes much…
Other Parts Discussed in Thread: TPS92512 I have a design using two TPS92512DGQs, each one driving five (5) high-power IR LEDs. A total of ten (10) IR LEDs are located each the PCB.
Each regulator block is as identical as possible (a reused schematic block…
I am using a TPS92512DGQ which is PWM dimmed. Typical frequency/dutycycle is 1 kHz/50%, so this is well within the specifications. During normal operation, I have got the device to work as intended.
However, in my application, the driver is activated…
Other Parts Discussed in Thread: TPS92512 , TPS92513 , LM3414 , LM3404 , LM3409 , TPS92640 E2e,
We have a customer that is using the TPS92512 in several projects. They are noticing a variation in output current between different channels of up to 12%. As an…
Other Parts Discussed in Thread: TPS92512 , TPS92512HV When operating the TPS92512 with an LED lamp that requires output voltage somewhat near the input voltage (say only 2-5V below) performance becomes unstable when dimming from full brightness (it's fine…
