DESCRIPTION
The MDW series consists of single output DC/DC converters that provides 20 watts of output power in a low
profile 2 x 1 x 0.4 inch package. These converters feature a 4:1 wide input voltage range of 9-36VDC or 18-
75VDC as well as positive or negative remote on/off, 1600VDC I/O isolation, trimmable output voltage, and
six-sided shielding. These converters are also protected against over current, over voltage, input under
voltage, and short circuit conditions. All models are particularly suited for telecommunications, industrial,
mobile telecom, and test equipment applications.

(2) Typical Value at Nominal Input Voltage and No Load
(3) Maximum Value at Nominal Input and Full Load
(4) Test by minimum Vin and Constant Resistive Load
(5) The ON/OFF control pin voltage is referenced to –Vin.
To order negative logic ON/OFF control add the suffix “R” (Ex. MDW48S5-4000R)
(6) Heat Sink is optional, consult factor for ordering details.
(7) The MDW Series can meet EN55022 Class A with an external capacitor in parallel with the input pins.
Recommended: 24Vin: NA
48Vin: 1µF/100V
(8) An external filter capacitor is required if the module has to meet EN61000-4-5.
The filter capacitor Wall Industries suggest: Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ.
Due to advances in technology, specifications subject to change without notice.

REMOTE ON/OFF CONTROL
The remote ON/OFF pin allows the user to turn the DC/DC power module on during a logic high and off during a logic low. Figure 3 gives several
examples of acceptable configurations. The remote ON/OFF pin is an open collector/drain logic input signal (Von/off) that has -Vin as the reference
voltage. If not using the remote on/off feature, open the circuit between the on/off pin and the -input pin to turn the module on.
REMOTE ON/OFF IMPLEMENTATION

Level Control Using TTL Output
Level Control Using Line Voltage
OUTPUT VOLTAGE ADJUSTMENT
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is
accomplished by connecting an external resistor between the TRIM pin and either the +Vout or -Vout pins. With an external resistor
between the TRIM and -Vout pin, the output voltage set point increases. With an external resistor between the TRIM and +Vout pin,
the output voltage set point decreases.
