有没有什么电路或者芯片可以使55伏电压转成15伏或者更低的电压
前提是功耗不能太大
用几个电阻分压功耗很大所以应该不考虑

LDO 吧
LDO is not a good choice for converting 55v to 15v.
It means very bad efficiency.
You can use a buck converter though it maybe complex.
ACDC or DCDC?
DCDC, buck is best for efficiency
buck DCDC

buck converter is one choice
片上可以用1/4 的charge pump产生55/4=14v
