Minmax's MIW1000-Series power modules are low-profile dc-dc
converters that operate over input voltage ranges of 4.5-9VDC,
9-18VDC, 18-36VDC and 36-72VDC which provide precisely regulated
output voltages of 3.3V, 5V, 12V, 15V, {5V, {12V and {15VDC.
The -40] to +71] operating temperature range makes it ideal for
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.
The modules have a maximum power rating of 3W and a typical
full-load efficiency of 84%, continuous short circuit, 45mV output ripple,
built-in filtering for both input and output minimize the need for external
filtering.

Test Configurations
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor
Lin (4.7uH) and Cin (220uF, ESR < 1.0[ 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.
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47uF ceramic capacitor.
Scope measurement should be made by using a BNC
socket, measurement bandwidth is 0-20 MHz. Position the
load between 50 mm and 75 mm from the DC/DC Converter.
Design & Feature Considerations
Maximum Capacitive Load
The MIW1000 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 1000uF
maximum capacitive load
for dual outputs and 4000
u
F
capacitive load
for single outputs.
The maximum capacitance can be found in the data sheet.
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 8.2uF for the 5V input devices, a 3.3uF for
the 12V input devices and a 1.5uF 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 3.3uF
capacitors at the output.

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 90C.
The derating curves are determined from measurements
obtained in an experimental apparatus.

The MIW1000 converter is encapsulated in a low thermal resistance molding compound that has excellent resistance/electrical
characteristics over a wide temperature range or in high humidity environments.
The encapsulant and unit case are both rated to UL 94V-0 flammability specifications.
Leads are tin plated for improved solderability.
