5 Watt Single Output, 5V Input Series DC/DC Converters
Description
Features
The CALEX 5 Watt DC/DC converters are ideal for use in high
performance computer data acquisition systems and board
level products. They are designed for systems that require a
regulated and isolated 5, 12 or 15 Volt auxiliary power source.
n
Low Profile Copper Case (0.375" High)
n
Six-side Shielded Case
n
Low Input/Output Noise Operation
The converters have efficiencies typically greater than
60%. A linear post regulator provides highly stable DC
outputs while minimizing noise.
n
Wide Input Voltage Range
n
Highly Regulated/Low Drift Output
n
Every unit is 100% tested prior to shipment and is
guaranteed under the CALEX 5 Year Warranty.

Low Noise, Trimable, Highly Stable Output
Efficiency > 74% For All Line Conditions
No Derating to 80°C Case Temperature
The converter features a 55kHz switching frequency that
provides outstanding regulation and efficiency at full load.
Six-sided Shielded, Low Thermal Gradient
Copper Case
The output is regulated with high loop gain pulse width
modulation control which provides linear regulator type
performance.

Overvoltage Protected Output
The output is resistor or trimpot trimable by ±10%, which
allows th WF to be set for +5.2 VDC in ECL applications.
Pulse By Pulse Digital Current Limit
The WF is protected from output shorts to ground by a high
speed digital, current limit circuit. The output is oervoltage
protected.
