DC to DC Converters
Distributed Power Supplies for Systems, Non-insulation Type
POL Converters iAA/iBA Series
Power supply systems for infrastructure devices used in communi-
cation networks primarily are expected to provide multi output, low
output voltage, higher efficiencies, and lower noise levels.
To meet these demands, the lineup did non-insulation type POL
(Point of Load) converter.
FEATURES
• Input voltage range (DC.3 to5.5V)
• The output voltage is a fixed type of 3.3V and 2.5V, and change-
able types of 0.75 to 3.63V.
• Heat sink is not required.
