►The
advantages of adding a heatsink are:
1. To improve heat dissipation and increase the
stability and reliability of the DC/DC converters at
high operating temperatures.
2. To increase operating temperature of the DC/DC
converter, please refer to Derating Curve.

Test Setup
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor Lin (4.7μH) and Cin (220μF, 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.

Technical Notes
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. 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 -100 μA. The maximum allowable leakage current of a switch connected to the on/off
terminal (Pin 4) at logic hight (2.5V 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 (Radj) between the Trim and +Vout or -Vout terminals. By adjusting Radj, the output voltage can be change by ±10% of the nominal output voltage.

Trim Up
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 to set the point as defined in 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 in the following equation:
Radj - down =
(36.667 × Vadj) - (33 × Vout )
Vout - Vadj
Vout: Nominal Output Voltage
Vadj: Adjusted Output Voltage
Units: VDC/KΩ
Overcurrent 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.
Overvoltage Protection
The output overvoltage 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
overvoltage. The OVP level can be found in the output data.

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.
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 a 33μF for the 12V input devices and a 10μF for the 24V and 48V devices.

Output Ripple Reduction
A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is
recommended to use 4.7μF capacitors at the output.

Maximum Capacitive Load
The MPW1000 series has 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 data sheet.
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℃. The derating curves are determined from
measurements obtained in a test setup.
