MAX765是不是,不能将12V转成负12V。因为技术手册上写，输入脚与输出脚的最大压差为20V.
The input voltage range is 3V to 16V. The output volt-
age is preset at -5V (MAX764), -12V (MAX765), or -15V
(MAX766); it can also be adjusted from -1V to -16V
using two external resistors (Dual ModeTM). The maxi-
mum operating VIN- VOUTdifferential is 20V |
