1 / 3 page  Standard Application Ordering Information Through-Hole PT3104A = 5 Volts PT3105A = 12 Volts PT3106A = 15 Volts Surface Mount PT3104C = 5 Volts PT3105C = 12 Volts PT3106C = 15 Volts (For dimensions and PC board layout, see Package Style 700.) Pin-Out Information • Power Density 15 Watts/in3 • Wide Input Voltage Range 18V to 40V • 81% Efficiency • 500 VDC Isolation • Small Footprint • No External Components Required Power Trends’ PT3104A (5V), PT3105A (12V) and PT3106A (15V) Isolated DC-DC Converters advance the state-of-the-art for board-mounted convert- ers by employing high switching frequencies greater than 650 KHz and planar magnetics and surface-mount construction. They fea- ture the industry’s smallest footprint, a power density of 15 Watts/in3, and operate at 80% efficiency. They are designed for Telecom, Industrial, Computer, Medical, and other distributed power applications requiring input-to-output isolation.
