Operational Features
• Ultra-high efficiency, 87% at full rated load current
• Delivers up to 20 amps of output current (100 Watts)
with minimal derating
• Wide input voltage range: 18V – 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
PQ24050QGA20 Module
Pr otection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from damage
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.40” (10.2mm), permits better
airflow and smaller card pitch
• Total weight: 1.2 oz. (34 grams)
• Flanged pins designed to permit surface mount solder-
ing (to avoid wave solder) using FPiP technique
Safety Features
• 2000V, 30 MΩ input-to-output isolation
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives
• Meets UL94V-0 flammability requirements
• NEBS and ETSI compliant
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
