Ultra-wide Input Range (10.8V to 264V AC or DC) Bias Power Supply Reference Design


Design files


The PMP20182 can handle 10.8V to 264V, AC or DC input voltage range and generate 12V/55mA output. With the use of UCC2813 PWM controller (up to 100% duty cycle) and Buck-boost topology, this ultra-wide input range power supply is made possible. This design uses a depletion MOSFET for fast startup - less than 50mS startup time is achieved with 12VDC input.Dimension of this board is 20mm (W) x 60mm (L) x 10.5mm (H).

  • Ultra-wide DC input - 10.8VDC to 264VDC
  • Ultra-wide AC input - 10.8VAC to 264VAC, 50/60Hz
  • High voltage Buck-boost converter design
  • Fast startup time with the use of depletion MOSFET
  • Board dimension is 20mm (W) x 60mm (L) x 10.5mm (H)
