Part Number: LMR16030PEVM Other Parts Discussed in Thread: LMR16030 Hello, I have encountered some technical problems when using the LMR16030 chip. Could you help me solve them? Design requirements: need to design DC-DC circuit. The input is 18V to 60V,…
hi ti:
I am looking for a DC-DC Boost/Buck converter chip solution and would appreciate your recommendation on a suitable model.
The specific operating conditions are: the input voltage ranges from 14V to 21V, requiring a stable output of 18V at 8A.…
Part Number: TPS552882 输入电压:12V,输出电压:19V/4.5A。单板的12V输入电源插入后,19V转5V的DC-DC先工作(电流不超过0.1A),然后通过按轻触开关接入MCU通过使能信号控制Jetson模组(19V供电)和其他DC-DC(19V输入)上电。通常几次上下电后(不是第一次上电就会坏),在按轻触开关使能Jetson模组(19V,电流不超过2A)和其他DC-DC上电(19V,电流不超过1A)的过程中,TPS552882RPMR DC-DC模块烧坏,大部分会发出滋滋的声音且模块发热…
Part Number: PMP41009 Other Parts Discussed in Thread: UCC28740 , Hello, I am debugging a self-designed flyback switching power supply with an input of 90-900VAC and an output of 24VDC. I use the UCC28740 chip and adopt the relevant power supply circuit…
Thank you for sharing the schematic.
From my understanding of the circuit the initial issue it that the input signal is bipolar where the ADS1119 is not designed to measure that signal. This is due to the analog input going below AGND. Please see Section…
Part Number: TPS6594-Q1
We use the single SOC solution (TDA4APE6), and use the PMIC TPS6594133ARWERQ1.
According to the EVM configuration document Powering Jacinto 7 SoC For Isolated Power Groups With TPS6594133A-Q1 + Dual HCPS (Rev. A)
GPIO9 of TPS6594133…
Insufficient load capacity of input power supply When the load is connected, if the rated power or current of the input power supply is insufficient, it will cause a voltage drop. For example, if the output impedance of a voltage regulator is large or…
