Part Number: TPS92640 Dear TI Team
My customer is considering dimming the TPS92640 in the following ways: (LED current is up to 500mA) ・ LED current 5mA ~ 500mA: The LED current is controlled by changing the voltage applied to the IADJ pin while the 100…
Part Number: TPS92640 Other Parts Discussed in Thread: UCC28810 , TPS92075 , LM3444 , LM3445 Hello guys,
One of my customers is looking for a reference design which can drive many LED in series with about 400V output using TPS92640 (Buck converter type LED…
Part Number: TPS92640 Hi team,
My customer want to generate 0.8V@500mA from 48V Vin with TPS92640.
Is it possible to generate such the low voltage with TPS92640?
It might be OK if lower switching rate such as 60kHz is selected as Fsw to be satisfied min…
Part Number: TPS92640 Hello experts,
I got question about start up with low analog dimming from customer.
My customer can't start up well when they set low analog dimming.
In datasheet P14, I found the discription related with proper start up as…
Part Number: TPS92640 Hi Everybody!
I have a question about "TPS92640: datasheet Fs: Switching Frequency.
SNVS902A.pdf TPS92640 datasheet wrote: ”nearly constant switching frequency”
But follow the output current, "switching frequency"…
Part Number: TPS92640 Other Parts Discussed in Thread: TPS92641 Hi team,
my customer is evaluating our device but from the datasheet it's not clear what's the minimum switching frequency. I read on most of our figures it's showed 500KHz or 1MHz, but…
Part Number: TPS92640 Other Parts Discussed in Thread: TPS92641 Hi,
In a design I am making at the moment I want to include the TPS92640.
Before using it I want to simulate the circuit in TINA, is there a simulation model of this part?
With kind regards…
