Specifications typical at Ta=+25℃, resistive load, nominal input voltage and 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 0-20 MHz.
All DC/DC converters should be externally fused at the front end for protection.
Other input and output voltage may be available, please contact factory.
To order the converter with heatsink, please add a
suffix H
(e.g.MPW1021H) to order code.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications subject to change without notice.

The
advantages of adding a heatsink are:
1. To help heat dissipation and increase the stability
and reliability of DC/DC converters at high
operating temperature atmosphere.
2. To upgrade the operating temperature of DC/DC
converters, 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.

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
)

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.
