The PQ60120HPA20 PowerQor
™
Peta half-brick converter
b
is a next-generation, board-mountable, isolated, fixed switch -
g
m
ing frequency DC/DC converter that uses synchronous recti -
fication 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 appli -
cation effort. The Peta series converters offer industry lead -
ing output current for a standard “half-brick” module. In
b
addition to typical single ouput voltage applications, the
Peta units can also be used to provide a wide input range
Intermediate Bus for IBA systems.
Operational Features
• Ultra-high efficiency, 92.5% at full rated load
• Delivers up to 240 Watts of output power (20A) with
minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
PQ60120HPA20 Module
Pr otection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection
• Active back bias limit prevents damage to converter
from external load induced pre-bias
