30 Amp, No Heatsink, Isolated DC/DC Converter
The PQ60050HGA30 PowerQor™ Giga converter
is a next-generation, board-mountable, isolated, fixed
switching frequency DC/DC converter that uses
synchronous rectification to achieve extremely high
conversion efficiency. The power dissipated by the
converter is so low that a heatsink is not required,
which saves cost, weight, height, and application
effort. The Giga series converters offer enhanced
useable output current in a standard “half-brick”
module. The Giga units also feature active current
sharing for N+1 and parallel applications.
PQ60050HGA30 Module
Operational Features
• Ultra-high efficiency, 90% at full rated load current
• Delivers up to 30 amps of output current with mini-
mal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient withstand
• Fixed frequency switching provides predictable EMI
performance
Protection Features
• Input under-voltage lockout disables converter at
low input voltage conditions
• Output current limit and short circuit protection
• Output over-voltage protection
• Thermal shutdown
Mechanical Features
• Industry standard pin-out configuration
• Industry standard size: 2.3” x 2.4”
• Total height only 0.40”, permits better airflow and
smaller card pitch
• Total weight: 2.1 oz. (59 grams)
Control 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
(Full-Feature modules)
Active current share for N+1 and parallel applications
External Clock Synchronization pin for better EMI
characteristics
Startup Synchronization pin for more consistent start-
up sequence
ORing FET drive supply for efficient ORing protection

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: 2.1 oz. (59 g) 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 consid-
ered part of the input/primary circuit.
