PQ60120QZB33
Contents
Operational Features
High efficiency, 96% at full rated load current
Delivers up to 33A of output current (400W)
Wide input voltage range: 35-75V, with 100V 100ms input voltage
transient capability
Fixed frequency switching provides predictable EMI performance
No minimum load requirement means no preload resistors required
Wide output voltage trim range (-50%), see trim section
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 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
PQ60120QZB33 Model
Control Features
On/Off control referenced to input side (positive and negative logic
options are available)
Mechanical Features
The PQ60120QZB33 PowerQor Zeta Quarter-brick
converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC/DC converter.
The Zeta series offers industry leading power density for
standard isolated DC/DC converters with both a wide
input range and a tightly regulated output. Targeted
for use in intermediate bus architectures, this module
supplies an isolated step down voltage from 35-75V to
12V and provides more available power and higher
efficiency than most competitive bus converters. RoHS
Compliant (see last page).
