Key Document


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)
