Technical Specification
Half
Brick
48Vin 3.3Vout 20A
20 Amp, No Heatsink, Isolated DC/DC Converter
The PQ48033HKA20 PowerQor⢠Kilo 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 Kilo series converters offer significant useable
output current in an economical standard âhalf-brickâ
module. The Kilo units also feature active current shar-
ingfor N+1 and parallel applications.
Operational Features
⢠Ultra-high efficiency, 89% at full rated load current
⢠Delivers up to 20 amps of output current with mini-
mal derating - no heatsink required
⢠Wide input voltage range: 35V â 75V meets or
exceeds all 48V bus standards
⢠Fixed frequency switching provides predictable EMI
performance
Mechanical Features
⢠Industry standard pin-out configuration
⢠Industry standard size: 2.3â x 2.4â
⢠Total height only 0.40â, permits better airflow and
smaller card pitch
⢠Total weight: 1.8 oz. (51 grams)
Safety Features
⢠2000V, 10 M⦠input-to-output isolation
⢠UL/cUL 60950 recognized (US & Canada), basic
insulation rating
⢠TUV certified to EN60950
⢠Meets 72/23/EEC and 93/68/EEC directives
⢠Meets UL94V-0 flammability requirements
