PQ50090QGB11 Datasheet, PDF (1/13 Pages) SynQor Worldwide Headquarters – Input under-voltage lockout disables converter at low input voltage

48V
Input
9.0V
Output
11A
Current
The PQ50090QGB11 PowerQor Giga converter is an
isolated, fixed switching frequency DC/DC converter
that uses synchronous rectification and a patented
topology to achieve extremely high efficiency and
power density. This 9Vout module provides 2,000Vdc
isolation and can deliver steady state output current
up to 11A. RoHS compliant (see last page).
Technical
Specification

• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see last page)
PQ50090QGB11
Protection Features
• Input under-voltage lockout disables converter at low input voltage
• Output current limit and short circuit protection protects converter &
load from permanent damage and consequent hazardous conditions
• Active back bias limit provides smooth startup with external load
induced pre-bias
• Latching output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Control Features
• On/Off control referenced to input side
(positive and negative logic options are available)
• Output voltage trim range of -10%, +10%
