DC/DC Conver ter
The PQ60525HTA04 PowerQor
™
Tera converter is a next-
generation, 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 mini-
mal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
PQ60525HTA04 Module
Contr ol Features
• On/Off control referenced to input side (positive and
negative logic options are available)
• Remote sense for the output voltage compensates for
output distribution drops
• Output voltage trim permits custom voltages and voltage
margining
Mechanical Features
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.43” (11.2mm), permits better air-
flow and smaller card pitch
• Total weight: 2.6 oz. (75 grams)
Safety Features
• 2250V, 30 M
Ω
input-to-output isolation
• UL/cUL 60950 recognized (US & Canada), basic insu-
lation rating
• TUV certified to EN60950
• Meets 72/23/EEC and 93/68/EEC directives
• Meets UL94V-0 flammability requirements
Pr otection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown

NOTES
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.
