The PQ24050QEx40 PowerQor Exa Quarter-brick
converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC-DC converter.
The Exa series offers industry leading power density
for standard isolated DC-DC converters with both a
wide input range and a tightly regulated output. This
module supplies an isolated step down voltage from
18-36 V to 5V and provides more available power
and higher efficiency than competitive converters.
This converter is available in openframe and encased
versions. RoHS Compliant (see last page).
Protection Features
• Input under-voltage lockout disables converter at low Vin conditions
• Output current limit
• Short circuit protection
• Protection from permanent damage and hazardous conditions
• Active back bias limit
