Specifications typical at +25°C, resistive load, nominal input voltage, rated output current unless otherwise noted.
Transient Recovery Time is measured to within 1% error band for a step change in output load of 75% to 100%.
Ripple & Noise measurement bandwidth is 0- 20MHz.
These power converters require a minimum output loading to maintain specified regulation. Operation at no-load
will not damage these devices, however they may not meet all listed specifications.
All DC/DC converters should be externally fused at the front end for protection.
Other input and output voltages may be available, please contact factory.
Specifications subject to change without notice.
To order the converter with Remote On/Off function, please add suffix ”-RC” (Ex: CG48S5-5000(A)-RC).
Due to advances in technology, specifications subject to change without notice.

DESIGN & FEATURE CONSIDERATIONS
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin and
off during a logic low. Negative logic remote on/off turns the module off during a logic low and on during
a logic high. To turn the power module on and off, the user must supply a switch to control the voltage
between the on/off terminal and the -Vin terminal. The switch can be an open collector or equivalent.
A logic low is -0.7V to 1.0V.
A logic high is 2.5V to 100V.
The maximum sink current at the On/Off terminal (Pin 3) during a logic low is 100 mA. The maximum
allowable leakage current of a switch connected to the On/Off terminal (Pin 3) at logic high (2.5V to
100V) is 5uA.
Output Voltage Trim
Output voltage trim allows the user to increase or decrease the output voltage set point of a module.
The output voltage can be adjusted by placing an external resistor (Radj) between the Trim and +Vout
or -Vout terminals. By adjusting Radj, the output voltage can be changed by ±10% of the nominal output
voltage.
A 10K, 1 or 10 Turn trimpot is usually specified for continuous trimming. Trim pin may be safely left
floating if it is not used.
Connecting the external resistor (Radj (up)) between the Trim and -Vout pins increases the output voltage
set point as defined by the following equation:
Radj (up ) =
(33 ∗ Vout ) − (30 ∗ Vadj )
Vadj − Vout
Connecting the external resistor (Radj (down)) between the Trim and +Vout pins decreases the output
voltage set point as defined by the following equation:
Radj ( down ) =
Vout:
Vadj:
Units:
(36.667 ∗ Vadj ) − (33 ∗ Vout )

Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary
to use a capacitor at the input to ensure startup.
A capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to
use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of 10uF for the
24V and 48V input devices.
Maximum Capacitive Load
The CG Series has a limitation of maximum connected capacitance at the output. The power module
may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time.
The maximum capacitance can be found in the “Output Voltage / Current Rating Chart.”
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current
limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit
inception, the unit shifts from voltage control to current control. The unit operates normally once the
output current is brought back into its specified range.
Output Over Voltage Protection
The output over voltage clamp consists of control circuitry, which is independent of the primary
regulation loop that monitors the voltage on the output terminals. The control loop of the clamp has a
higher voltage set point than the primary loop. This provides a redundant voltage control that reduces
the risk of output over voltage. The OVP level can be found in the “Output Voltage / Current Rating
Chart.”
Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over
the module, and board spacing. To avoid exceeding the maximum temperature rating of the components
inside the power module, the case temperature must be kept below 105°C. The derating curves are
determined from measurements obtained in an experimental apparatus.

TEST CONFIGURATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0Ω at
100 KHz) to simulate source impedance.
Capacitor Cin offsets possible battery impedance.
Current ripple is measured at the input terminals of the module. Measurement bandwidth is 0-500 KHz.
Peak-to-Peak Output Noise Measurement Test
Use Cout = 1.0uF ceramic capacitor.
Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz.
Position the load between 50mm and 75mm from the DC/DC Converter.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as possible across the load will give the best ripple
and noise performance. To reduce output ripple, it is recommended to use 4.7uF capacitors at the
output.
