Bridgewater, N.J.Enpirion has introduced a 2-amp buck-mode device dubbed the EN5322QI that is being touted as a replacement for inefficient linear regulators to help designers meet EPA Energy Star 4.0 requirements.
The EN5322QI features Enpirion's integrated inductor technology. The EN5322QI comes in a tiny 6mm x 4mm x 1.1mm QFN package and integrates all converter functions. It requires a single input and single output ceramic filter capacitor. The converter integrates MOSFET switches, control and compensation, and the inductor.
The device has a wide 2.4V to 5.5V input range and has a VID programmable output range from 0.6V to 3.3V. The EN5322QI is capable of sourcing a continuous 2A over the entire industrial temperature range.
With a total footprint of less than 60mm², the EN5322QI delivers a power density of more than 70 watts per square inch, and uses a type III voltage mode control scheme.
Pricing: Set at $2.23 in quantities of 1000-pieces.
Availability: Parts are sampling now.
