Power: Lead-Free, Plug-In Power Modules Cut Size In Half

The PTN78 wide-input, non-isolated modules are 50% smaller than their predecessors in the PT78 family. The PTN78000, PTN78060, and PTN78020 provide resistor-adjustable 2.5 to 12.6 V and 1.5, 3, and 5 A from input voltages of 7 to 36 V. Full-load efficiency is 85% with a 5-V output. Each model is lead-free and RoHS-compliant. The PTN78000 measures 18.9 by 12.5 by 8.5 mm, the PTN78060 is 25.2 by 15.7 by 9 mm, and the PTN78020 is 37.9 by 22.1 by 9 mm. Suggested 1000-unit pricing runs $8, $11, and $15, respectively.
