Part Number: LM3409 Other Parts Discussed in Thread: TPS92518 , TPS92515 , TPS92515-Q1 Hello Team,
Do you have a similiar chip to LM3409, that have 10,000:1 PWM Dimming Range. That is a key performance for our application.
I need the low voltage input…
Part Number: TPS92515HV Other Parts Discussed in Thread: TPS92515 , TPS92515-Q1 , I just made a circuit board for a dimmable line light. Now the chip TPS92515HV is out of stock for months. Are there alternatives which are pin compatible?
Thanks in advance…
Hi Jeff,
The two super-caps are in series and each one is 25F/2.7V. The charging current is 1A. And the block diagram is attached below. Our customer requires all the sockets to be qualified for Automotive applications. So we intend to choose TPS92515…
Part Number: TPS92515 Hi Sir,
We plan use TPS92515-Q1 designd for Sequential Turn with BC846B. There are frequency problem need your comfirm. In datasheet figure result description fixed input voltage, the device operates at the maximum frequency at…
Other Parts Discussed in Thread: TPS92515-Q1 Dear support team
My customer performed short/open test of shunt resistor and open test of inductor.
It was expected that the output voltage and switching of FET do not appear because current sense does…
Part Number: TPS92515HV Other Parts Discussed in Thread: LM3409 Hello,
we're experimenting an issue with 10KHz PWM signal: if it goes to 0% we are not able to get a good output switching signal any more.
The datasheet says ( www.ti.com/.../tps92515…
