1. How to make the output HV is tunnable with the control of MCU(PWM for wxample)? The HV range is 50-200V, is tunable.

2 How to Inverting the Boost HV to -200V? I need a negtive HV output.

Thanks.

Hi Steven,

Please take a look at the attached design. It is tunable for -50V to -270V. The power topology is an inverting buck-boost with charge pumps used for quadrupling.

Thanks,
Ryan
