DC/DC Conver ter
The PQ60525HTA04 PowerQor ™ Tera converter is a nextgeneration, board-mountable, isolated, fixed switching fre m quency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The module is ideally suited to support the IEEE 802.3af standard for Power Over LAN and VoIP applications. The Tera series converters offer the maximum useable output current for any standard “half-brick” module. The Tera units also feature b active current sharing for N+1 and parallel applications.
Operational Features
• Ultra-high efficiency, 92% at full rated load current • Delivers up to 200 Watts of output power with minimal derating - no heatsink required • Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance

1) Pins 1-4, 6-8, A-C are 0.040” (1.02mm) diameter. with 0.080” (2.03mm) diameter standoff shoulders. 2) Pins 5 and 9 are 0.080” (2.03 mm) diameter with 0.125” (3.18mm) diameter standoff shoulders. 3) Pins 3, A, B & C only included in Full-Feature models. 4) Other pin extension lengths available. Recommended pin length is 0.03” (0.76mm) greater than the PCB thickness. 5) All Pins: Material - Copper Alloy Finish - Tin/Lead over Nickel plate 6) Undimensioned components are shown for visual reference only. 7) All dimensions in inches (mm) Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm) x.xxx +/-0.010 in. (x.xx +/-0.25mm) 8) Weight: 2.6 oz. (75g) typical 9) Workmanship: Meets or exceeds IPC-A-610C Class II 10) UL/TUV standards require a clearance greater than 0.04” (1.02mm) between input and output for Basic insulation. This issue should be considered if any copper traces are on the top side of the user’s board. Note that the ferrite cores are considered part of the input/primary circuit. 11) The flanged pins are designed to permit surface mount soldering (avoiding the wave soldering process) through the use of the flanged pin-in-paste technique.
