Abstract
A high-voltage module HVMD includes: an error amplifier configured to output a control signal based on a reference signal Vin and a feedback signal; a high voltage output circuit configured to output a high voltage Vout for supply based on the control signal; and a feedback circuit configured to output the feedback signal based on the high voltage Vout for supply. Here, the feedback circuit includes: a first partial circuit configured to receive an input of the high voltage Vout for supply and to output an intermediate signal, the first partial circuit including a resistance element; and a second partial circuit configured to receive an input of the intermediate signal and to output the feedback signal. The high-voltage module HVMD further includes a substrate SUB including: a high voltage substrate region where the high voltage output circuit and a part of the first partial circuit are mounted.
