5 Watt Dual Series DC/DC Converters
Description
Features
n
The versatile 5 Watt Dual Output converter is particularly
suitable for use in microprocessor systems where 5 Volts is
the primary power source, and where a low noise plus and
minus output voltage is required.
Low Input/Output Noise Operation
n
Low Profile Case (0.38")
n
Isolation Capacitance of 50 pF
The shielded transformer provides low I/O capacitance
and high common mode input to output isolation.
n
Extended Operating Temperature Range of
-40°C to +100°C.
The low guaranteed output noise of 20mV P-P maximum is
achieved by a built-in linear post regulator.

n
Fixed Frequency Operation
5 Year Warranty
Available in standard 6 sided shielding, or the -5 model
which has 5 sided shielding and is water washable.
Each converter is completely specified, fully ATE tested,
