Packaging

The APM81815 is a highly integrated, 1.5 A and low EMI DC-DC regulator designed for 48V systems. Allegro's innovative packaging technology allows for the integration of the converter along with EMI capacitors to offer a power supply that will meet very stringent EMC specifications without the need for additional EMI filters.

Due to the high level of integration, the APM81815 minimizes the number of additional components required to enable a high-powered DC-DC converter to be located in very space-constrained applications. The APM81815 is automotive qualified to a Grade 1 temperature rating, which allows this regulator to survive harsh environments without degradation.

  • VIN operating range: 5 to 72 V
  • 1.5A continuous output current
  • Integrated Vin and Boot Cap to reduce component count and achieve ultra-low EMI
  • Thermally enhanced and space saving 4 mm × 4 mm × 2.1 mm wettable flank QFN package
  • 28 μA no-load quiescent current (48 VIN to 12 VOUT)
  • 2.15 MHz internally fixed and adjustable from 400 kHz to 2.4 MHz

The APM81803 features a 24-pin, 4 mm × 4 mm x 2.1mm QFN package with exposed thermal pads and wettable flank, (suffix NB).
