Part Number: TPS92682-Q1 Tool/software: Hello, expert,
we are currently using the scheme of TPS92682 * 1 + TPS92520 * 3, two-phase Boost +6-phase Buck constant current;
The boost voltage is 51V; PWM frequency of TPS92520: the 215hz
Load configuration…
Part Number: TPS92682-Q1 Tool/software: Hello, expert: I am currently designing an LED driving solution using the TPS92682 chip. I would like to know how to test the stability of the loop (the gain-phase characteristics of the loop) when this chip operates…
Part Number: TPS92682-Q1 Tool/software: Hello, expert.
The SPI waveform of TPS92682 is also measured. The waveform of TPS92520 is found to be different. The rising and falling time is relatively long. Our configuration is as follows: 1 TPS92682 +3 tps92520…
Part Number: TPS92682-Q1 Tool/software: Hi,
i was searching for calculator for tps92682-Q1 in CC mode. It is not available in ti.com product website.
It would be helpful if i get the link for the same.
Part Number: TPS92682-Q1 Tool/software: Hello, expert,
We need to know this parameter to do a register initialization operation, thank you.
We want to know that the input voltage of TPS92682/TPS92520 decreases, and the register contents of TPS92682/TPS92520…
Part Number: TPS92682-Q1 Other Parts Discussed in Thread: TPS92530-Q1 , Tool/software: Hello TI E2E Support team,
The TPS92682-Q1 works as 1st-stage boost CV of Boost-Buck LED driver structure.The TPS92530-Q1 is the 2nd-stage buck CC.
[fail-safe mode…
Part Number: TPS92682-Q1 Tool/software: I have been working with the TPS92682 to drive a string of LEDs and plan to use the IC in Constant Current (CC) mode . Before moving to real-life implementation, I wanted to simulate the circuit using the PSpice…
Part Number: TPS92682-Q1 Tool/software: Dear TIer,
According to Figure 7.3, the synthesized signal (SLOP & iSW) cannot trigger VCOMP. How can GATEx determine whether it is on or off?
Part Number: TPS92682-Q1 Other Parts Discussed in Thread: TPS92691-Q1 , TPS92691 Tool/software: Hello,
We have made a design that runs a 37V@1A forward voltage LED with a 48V power supply nominal, max 52V.
I've followed the design guide for TPS92691-Q1…
Part Number: TPS92682-Q1 Tool/software:
sig1 is the output PMOS PWN control Vgs voltage
sig3 is the output circuit, there is a very big spike, what should i do to improve this problem. the band width of this spike is about 30ns.
