Key Document


The PMP11090 reference design is a compact and thermally efficient design intended to step down a wide range of AC inputs (105VAC to 440VAC). This non-isolated Buck design incorporates the UCC28710 PSR controller and TLV70450DBVT LDO. The PMP11090RevA board are designed with complete standard components (including magnetics).

  • 105VAC to 440VAC, 50/60Hz input 24V/400mA and 5V/20mA outputs
  • Less than 60 degree C temperature rise on all parts
  • 1% output voltage regulation accuracy
  • Utilize all standard components (including magnetics)
  • Compact board size with 25mm W x 45mm L
  • Test report available
