Minmax's S2E00 Model 1.5W DC/DC's are specially
designed to provide 30mA output ripple, continuous short
circuit in a low-profile 24-pin DIP package.
The series consists of 18 models with input voltages of
5V, 12V and 15VDC which offers regulated output voltages of
5V, 12V, 15V, {5V, {12V and {15VDC.
The -40] to +85] operating temperature range makes
it ideal for data communication equipments, mobile battery
driven equipments,distributed power systems,
telecommunication equipments, mixed analog/digital
subsystems, automatic test instrumentation and industrial
robot systems.

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 0.33uF 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.

Load
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 2.2uF for the 5V input devices, a 1.0uF for
the 12V input devices and a 0.47uF for the 15V devices.

Design & Feature Considerations
Maximum Capacitive Load
The S2E00 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 220uF
maximum capacitive load for each dual outputs and 470uF
capacitive load for single outputs.
The maximum capacitance can be found in the data sheet.
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.
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 95°C.
The derating curves are determined from measurements
obtained in an experimental apparatus.
