Product Number: ADP5071
I am trying the ADP5071 to boost the voltage of the lithium battery to plus or minus 18V, and the function of the PCB has been realized.
However, my system is a low power system and needs to turn off the output through EN1\EN2 when not using the 5071. I found that after I gave the EN pin a low level through the MCU, the chip output still has +10V and -8V. What is the situation? I have pulled the enable end down and connected the pull-down resistor. Schematic diagram period manual recommended circuit
