6.5V to 28Vin, 5V 1.3A out DC/DC Reference Design Module in TO220 Package


Design files


The PMP4467 is a 6.5V to 28Vin, +5Vout, 1.3A reference design module which is implemented in TO220 package, targetting for general LDO replacement. The design includes a non-synchronous step-down regulator TPS5405. The solution has high efficiency, good line, load regulation. The power module was designed with minimized components for cost sensitive applications.

  • Non-synchronous Buck topology
  • High efficiency, up to 92% at low input votage and full load
  • Good line regulation, less than  ±0.03%
  • Good load regulation, less than ±0.04%
  • Low cost solution with minimized component numbers
  • TO220 package P2P with LM78M05
