Part Number: LM5022
我使用 WEBENCH ® POWER DESIGNER 进行电路设计，使用LM5022，设计参数是VIN =14-24V；Vout=50@2A，开关频率：200kHZ，Temp：60℃，Cout：680uF，推荐使用的MOSFET型号是FDWS86068-F085； WEBENCH ® POWER DESIGNER 计算出MOSFET的开关损坏和导通损耗分别是525mW和473mW；但是和我在LM5022数据手册里面推荐的计算公式计算出的相差很多，按照公式计算如下…
Hi Lydia:
There is already internal 1kOhm resistor for discharge, and our EVM design just has a 0 ohm resistor here between VEE_DIS and VEE.
For example, in my circuit, VEE_DIS is a 750K resistor. Is this a VGL Fail issue?
If so, what is the cause?

Part Number: TPS61088 Hello, I built a 2.7V to 5V boost circuit based on the schematic provided by Power Designer. However, it can only output around 0.2A at most currently. I need it to output 5V 3A. Which components affect the output capacity?
