Part Number: TPS54040 Good day, We use TPS54040DGQ in our projects. And we find out that we have a heating problem with that. Below you could find parameters of our circuite. Input voltage is 12VDC or 24VDC Output voltage is 5.5VDC Swiching freq. resistor…
Part Number: TPS54040 Other Parts Discussed in Thread: LMR36510 , LMR33610 , LM3489 , TPS64200 , LM3475 We are using the TPS54040 in an application which requires operation at 100% duty-cycle with very light load for up to 50ms at a time. Using the recommended…
Part Number: TPS54040 Other Parts Discussed in Thread: LM5164 Hi Team,
Generally speaking, customers have a need to use a buck converter to ground the original output terminal to achieve a negative voltage output function. Now my customer wants to confirm…
Part Number: TPS54040 Dear Support team
I checked the input current by swinging the load of the TPS54040 from 10 mA to 100 mA.
Although the input current decreases linearly as Vin is increased, it seems that it increases only when Iout =10 mA. And…
Part Number: DRV8305 Other Parts Discussed in Thread: TPS54040 Hi,
Can someone please throw in some light on the 2 questions that I am having ?
#1. There are 3 DRV8305 variants. (no LDO, 3.3V LDO and 5V LDO variant)
Does the PGOOD signal behave…
Hello
It think that it should be OK to substitute one regulator for the other. The major difference is the current rating.
You will probably have to adjust the inductor value and the compensation.
You should use either the Webench tool or the component…
Part Number: TPS54040 Hi, Could you tell me about Issavg. Is Issavg the same value as Iss=2uA? If that is not the case, please tell me how Issavg calculates. Best Regards, Yusuke/Japan Disty
