Part Number: TPS922054
Hello, I have used your company's TPS922054 chip to make an LED driver board. The schematic diagram is as follows:
The input voltage range is set at 24 to 28V. I have tried the switching frequency at 2MHz and 680KHz (the calculation…
Part Number: LDC1101
Hi,
I want to detect the vibration characteristics of a 10mm-thick aluminum alloy crossbar with a measurement range of 0.5–3mm, using the LHR (High-Resolution Inductance) mode. The sampling rate is set to 10 kSPS.
Now I need…
Part Number: TPS25750EVM Other Parts Discussed in Thread: BQ25731 , Hi Ti Team
If I use Type-C input voltage (PD Max 100W), will it use BATT (TP3) as the output?
Can I pin out a wire from the TP3 pin and charge a device, such as a tablet or laptop?
If it…
Part Number: TPS62A01
您好！在 WEBENCH ® POWER DESIGNER 看了下，没有推荐前馈电容。这个值是按规格书上的选120PF吗？
Input:
DC 3.4 V - 4.4 V
Output:
3.3 V at 0.1-0.5 A 是不是3.3V不需要这个前馈电容呢。

Hi ,
Wang Xuesong 说： Both Experiment 2 and Experiment 1 adopt current loop feedback regulation. However, Experiment 2 states that when the AC current reference (ac_cur_ref) is 0.045, the input current is 2.4 A; Experiment 3 describes that when ac_cur_ref…
Part Number: LM5127-Q1 I am using the LM5127QRGZRQ1 in my design, with the following operating conditions:
Input Voltage (Vin): 20V
Output Voltage (Vout): 2.6V
Output Current (Iout): 16.8A
However, I couldn't find a reference efficiency curve in…
这可能与当初EVM设计时，设定的典型值有关。并不是特定的。
下面是我找到的一些信息。
I did not personally design that EVM, but it is not uncommon to have restricted input voltage range. In this particular case, it has to do with the external UVLO set by R4 and R5. The typical start voltage is…
Part Number: LM62460 Other Parts Discussed in Thread: LM61480 Hi:
I used two LM62460 / LM61480 buck ICs for 25V to 12V and 25V to 18V；
The 25V to 12V circuit often burned out in input pin（VIN1&VIN2）when IC powered on.The 25V to 12V circuit had never happened…
Part Number: TPS53355
Hi Experts,
I build a TPS53355 circuit, converting 12V to 3.3V.
The problem is that no voltage at output. I have checked the 12V input power, EN voltage and VREG voltage, all correct. The output loading is about 900mA, no short…
