Part Number: TPS54160 Other Parts Discussed in Thread: PMLKBUCKEVM Hi team,
I'm testing the efficiency of PMLKBUCKEVM with vin=24V, Vout=3.3V, Cout=220 µF, fs=250kHz. The result is shown in the following picture. I wondering why the trend of the efficiency…
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: TPS54160 Hi, TI Support Team
My BUCKEVM is broken and experiencing the following problem.
1.For unknown reason the output capacitor C16 was broken down, and the test resistance size was 2 ohm, while…
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: TPS54160 Hi, TI Support Team
Yesterday I tested the TPS54160 on PMLKBUCK EVM and nothing went wrong.
However, today when I test the TPS54160 on PMLKBUCK EVM, the output voltage keeps on about 1.5V…
Part Number: PMLKBUCKEVM Hi, TI support team.
In experiment 2, I want to calculate buck input current ripple.
How can choose from these two formulas? I don't know how to judge high and low capacitance.
If define High capacitance as J12 SH(Cin=4.7…
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: TPS54160 Hi, support team
When testing PMLKBUCKEVM, it was found that at light loads, the Vnode waveform seems to have some oscillations at higher input voltages.
CH1 represents Vin, CH2 represents…
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: TPS54160 Hi,
Currently i'm doing the experiment 1 test 1, Vin 24V, Vout 3.3V, Iout change from 0.1A to 1.5A.
i find when the Iout is lower than 0.7A, the Vsw will show some weird waveform. shown…
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: INA139 I am trying to locate two accessory boards for the Buck and LDO PMLK -- a "TI-PMLK INA139 current shunt sensing board" and a "TI-PMLK current transformer sensing board". Part numbers…
Part Number: PMLKBUCKEVM Dear expert:
I want to calculate buck input current ripple. How can choose from formula(5) and formula(6)? I don't know how to judge high and low capacitance,can you kindly teach me please?
Part Number: PMLKBUCKEVM Other Parts Discussed in Thread: TPS54160 Hi, team
Can you help me solve the following problems when I measure the PMLKBUCKEVM board? Thank you
1）How to understand the formula calculating the input current ripple in the page…
