This is a low-cost DC-HV DC converter built using TL3843 Low-Power Current-Mode PWM Controller from TI. Screw terminal connectors are provided for input and output, onboard LED D1 indicates the input supply. The project provides 200V DC @ 20mA output from 12V DC supply input.

Note: Output of this project is 150V @ 50mA DC to 200V @ 20mA DC, this project also can provide lower voltage outputs, read TL3843 data sheet for configuration.
HIGH VOLTAGE: Dangerous voltage exists until power light is off. Wait at least 1 minute after input power is disconnected before touching the board.

Features

  • Operating Power Supply 12V DC @ 1A (Range 10V to 15V DC)
  • Output 150V DC @ 50mA to 200V DC @ 20mA
  • Operating Frequency 40Khz
  • Over Current Protection
  • D1 Power LED
  • Screw Terminal Connectors for Input and Output
  • PCB Dimensions 61.28 x 36.04 mm
