Brick
Half
48Vin 1.8Vout 40A
40 Amp, No Heatsink, Isolated DC/DC Converter
The PQ48018HGA40 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.
PQ48018HGA40 Module
Operational Features
• Ultra-high efficiency, >85% at full rated load current
• Delivers up to 40 amps of output current with mini-
mal derating - no heatsink required
• Wide input voltage range: 35V – 75V meets or
exceeds all 48V bus standards
• Fixed frequency switching provides predictable EMI
performance
Protection Features
• Input under-voltage lockout and over-voltage
shutdown protects against abnormal input voltages
• 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
