Description

The PMP30122 reference design is for an input voltage range from 40V to 55V with an output voltage of 28V@ 0.5A. This design is also tested for a maximum peak output current of 1A. The buck converter is dedicated to supply sensitive loads on one hand - and on the other hand equipped w/ input filter to attenuate reflected ripple to source. The layout itself is made for lowest radiated noise: no VHF ringing at the switch node. Feedback divider is calculated for 24V: 28V and 32V output.
