Minmax's MKW1000 series of DC/DC converters, comprising 24 different models, is designed for a wide range of applications including data
communication equipments, mobile battery driven equipments, distributed power systems, telecommunication equipments, mixed analog/digital
subsystems, process/machine control equipments, computer peripheral systems and industrial robot systems.
Packing up to 10W of power into a 2x1x0.4 inch package, with efficiencies as high as 83%, the MKW1000 has wide input ranges of 9-18VDC,
18-36VDC and 36-75VDC and is available in output voltages of 3.3V, 5V, 12V, 15V, 24V, {5V, {12V and {15VDC.
Other feathers include continuous short circuit protection, six-sided shielded case and EN55022 Class A conducted noise compliance minimize
design-in time, cost and eliminate the need for external filtering.
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.
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 < 1.0[ at 100
KHz) capacitor of a 15uF for the 12V input devices and a
4.7uF for the 24V and 48V devices.
Maximum Capacitive Load
The MKW1000 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.
For optimum performance we recommend 470uF
maximum capacitive load for dual outputs and 2200uF
capacitive load for single outputs.
The maximum capacitance can be found in the data sheet.
