Product Brief: Powereta™ – Single Output High Current Double-P Quarter Brick
Powereta™ iQP Series Double-P Quarter Brick
48V Input, 5V/50A/250W DC Output
The Powereta™ iQP Series offers an industry standard
Double-P quarter brick high current power module with true
useable output power. The iQP series power modules are
ideally suited for high-density distributed power architectures
where the demands of voltage and substantial load mandate
the creation of a robust local intermediate 5V distribution bus.
Its 92% full load efficiency (93% at 70% load) and superior
thermal performance make the iQP Series of power modules
ideally suited for tight space and power-hungry applications in
demanding thermal environments. This rugged building block
is designed to serve as the core of your high reliability system.
A wide output voltage trim range, -20 to +10%, and remote
sensing are standard features enhancing versatility.
