DESCRIPTION
The MM series power modules are low-profile dc/dc converters that offer up to 30 watts of output power in a 2 x 1.6 x 0.37 inch package.
These converters operate over input voltage ranges of 9-18VDC, 18-36VDC, and 36-75VDC. This series also provides regulated single
and dual output voltages of 3.3, 5, 12, 15, ±12 and ±15VDC. Other features include remote on/off control, output trim function, six-sided
shielding, and efficiencies up to 89%. All models are over voltage, over temperature and short circuit protected. The EN55022 Class A
conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components. These converters are
best suited for data communication equipment, mobile battery driven equipment, distributed power systems, telecommunications
equipment, mixed analog/digital subsystems, process/machine control equipment, computer peripheral systems, and industrial robot
systems.
SPECIFICATIONS: MM Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

NOTES
1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
2. The MM series requires a minimum output loading to maintain specified regulations. Operation under no-load
conditions will not damage these devices, however they may not meet all listed specifications.
3. All DC/DC converters should be externally fused at the front end for protection.
4. Other input and output voltages may be available, please contact factory.
5. Heat-sink is optional, please consult factory for ordering details.
Due to advances in technology, specifications subject to change without notice.

The encapsulant and unit case are both rated to UL 94V-0 flammability specifications. Leads are tin plated for improved
solderability.

DESIGN & FEATURE CONSIDERATONS
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and turns the module off
during a logic low. 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 -1V to 1.0V.
A logic high is 2.5V to 100V.
The maximum sink current at the on/off terminal (pin 4) during a logic low is -100μA. The maximum allowable leakage
current of the switch at the on/off terminal (pin 4) during a logic high (2.5 to 100V) is 5μA.
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 (R) between the Trim and +Vout or –Vout terminals. By adjusting R, 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 being
used. Connecting the external resistor (Rup) between the Trim and –Vout pins increases the output voltage to set the point as
defined in the following equation:
(33 x Vout) - (30 x Vadj)
Rup
=
Vadj - Vout
Connecting the external resistor (Rdown) between the Trim and +Vout pins decreases the output voltage set point as defined
in the following equation:
(36.667 x Vadj) - (33 x Vout)
Rdown
=
Vout - Vadj

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.
Over Voltage Protection
The output over voltage clamp consists of control circuitry that is dependent on 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 an output over voltage. The OVP level can be found in the
protection specifications.

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 100KHz)
capacitor of a 33μF for the 12V input models and a 10μF for the 24V and 48V input models.

Maximum Capacitive Load
The MM 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. For optimum performance we recommend
330μF maximum capacitive load for 12V and 15V outputs and 10,000μF capacitive load for 3.3V and 5V outputs. The
maximum capacitance can be found in the Output Voltage / Current Rating Chart.
TEST CONFIGURATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7μH) and Cin (220μF, ESR < 1.0Ω at 100KHz) to simulate

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.
