DC/DC Converter
The PQ24033QGL25 PowerQor⢠Giga quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses syn-
chronous rectification to achieve extremely high conver-
sion efficiency. The power dissipated by the converter is
so low that a heatsink is not required, which saves cost,
weight, height, and application effort. All of the power
and control components are mounted to the multi-layer
PCB substrate with high-yield surface mount technology.
The QGL series employs a very low profile to accommo-
date tight spacing requirements. RoHS 5/6 compliant
(see page 12).
Operational Features
⢠Ultra-high efficiency, 87% at full rated load current
⢠Delivers up to 25 amps of output current with minimal
derating - no heatsink required
⢠Wide input voltage range: 18V â 36V meets or
exceeds all 24V bus standards
⢠Fixed frequency switching provides predictable EMI per-
formance
⢠No minimum load requirement means no preload resis-
tors required
Mechanical Features
⢠Industry standard quarter-brick pin-out configuration
⢠Industry standard size: 1.45â x 2.3â (36.8x58.4mm)
⢠Total height less than 0.335â (8.5mm), permits better
airflow and smaller card pitch, meets NTT reqs.
⢠Total weight: 1.2 oz. (34 grams)
⢠Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
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 volt-
age margining

Protection Features
⢠Input under-voltage lockout disables converter at low
input voltage conditions
⢠Output current limit and short circuit protection protects
converter and load from permanent damage and conse-
quent hazardous conditions
⢠Active back bias limit prevents damage to converter
from external load induced pre-bias
⢠Output over-voltage protection protects load from dam-
aging voltages
⢠Thermal shutdown protects converter from abnormal
environmental conditions
Safety Features
⢠2000V, 30 M⦠input-to-output isolation provides
input/output ground separation
⢠UL/cUL 60950 recognized (US & Canada), basic
insulation rating
⢠TUV certified to EN60950
⢠Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in userâs end product
⢠Board and plastic components meet UL94V-0 flamma-
bility requirements
⢠NEBS and ETSI compliant
