Part Number: TPS53681EVM-002 Hi,
We are developing a POL converter with 1.2V/300A, and the parameters are very simiary to TPS53681EVM-002. Can you provide for us the PCB source documents of power stages schematic and transient load schematic?
We would…
Part Number: TPS53681EVM-002 Hi, We tested TPS53681EVM-002 and found low-frequency periodic deviation of output voltage. The frequency of the deviation is around 30kHz. (Please see attached file.) The test condition is VIN:12V、VOUT:0.9V、IOUT:50A、Phase:6…
Part Number: TPS53681EVM-002 Hi,
I want to test DCM 1-phase operation on this EVM. The setting in Fusion I used are shown below. With 2A load current, only phase one has PWM signal. However, the phase one still works in CCM from measured inductor current…
Part Number: TPS53681EVM-002 Other Parts Discussed in Thread: TPS53681 , TPS536C7 Hi TI expert,
I'm confused about below circuits you used in EVM:
1. Sometimes you're using a comparator to drive the N-MOS, sometimes direct drive is used. Why are there…
Part Number: TPS53681EVM-002 Hi,
Fusion software cannot find this device after applying 12V to the EVM input. I checked TP8 and I can see 3.3V voltage. I tried different scanning modes. However, it didn't work. Do you know how to solve this problem? Below…
Part Number: TPS53681EVM-002 Other Parts Discussed in Thread: TPS53681 Hi,
Are there any test points where I can see each phase inductor current or total inductor current? Also, how should I probe load transient current by using the transient loads on…
Part Number: TPS53681EVM-002 Other Parts Discussed in Thread: TPS53681 , CSD95490Q5MC Hi team,
In Fusion Digital Power Designer, we can see the resgister "MFR_SPECIFIC_20" that is not listed on TPS53681 datasheet.
1. What should be written in this…
Part Number: TPS53681EVM-002 Tool/software: WEBENCH® Design Tools The GUI has very small font on many of the voltage adjustment buttons.
How can this be adjusted ??
Thank you in advance.
Part Number: TPS53681 Hello, Datasheet recommends the power-up sequence and power-down sequence as follows. But, at TPS53681EVM-002, 12V is provided first and other power supply voltages are generated from the 12V. So, the EVM does not follow the recommended…
