DC-DC Converter
50W, Isolated, 4- Regulated Outputs
Description:
The SCP-5259 Series DC-DC converters are high-density self-contained multi-
output power supplies. They incorporate Sensitron’s proprietary technology which
enables 4 independently regulated outputs and extremely low input ripple current.
These power supplies will operate at a base plate temperature of –55 - 125 OC over
the DC input range of 15V to 50V. The outputs can be inhibited by a logic level
signal. One of the four outputs can be user programmed via a voltage source or a
resistor value to ground.
Features:
· 15V to 50V Input Voltage Range
· 80V Input Transient for 1 Sec.
· -55 to +125OC operating range
· Four Fully Regulated Outputs
· One programmable Output
· Fixed Frequency Switching
· Synchronous Rectification
· High Efficiency
· Very Low Input Ripple Current (100ma)
· Self contained, No external components
· Logic Control
· Fast Response
· Thermal Shutdown (optional)
Packaging
· Low Profile Aluminum Case 0.6” x 2.4” x 4.2”
· Cold plate mounting
· PCB mounting
· Near-Hermetic (Moisture and Contamination Resistant, Gross Leak Tested)

NOTES
1. Input protected by diode connected between pins 2 (anode) and 1(cathode). Fast acting
disconnect device is recommended.
2. Followed by 300s operation at reduced power (80% load)
3. Output 4 will follow the Trim Voltage. Internal setting = 2.2V, can be lowered by connecting
the Trim Resistor to the Common Ground.
4. Total power will be gradually reduced for temperatures exceeding the threshold level.
5. Vertical orientation in free air.
