MIW1500 Series

3 Watts 2 :1 Wide Input Range DC/DC Converters

Single and Dual Outputs

Key Features

Ÿ High Efficiency up to 82%

Ÿ 2:1 Input Range

Ÿ I/O Isolation 1500VDC

Ÿ Industry Standard Pinout

Ÿ SMT Technology

Ÿ Short Circuit Protection

Ÿ EMI Complies With EN55022 Class A

Ÿ MTBF > 1,000,000 Hours

MIW1500-Series power modules are low-profile

dc-dc converters that operate over input voltage ranges of

4.5-9VDC, 9-18VDC, 18-36VDC and provide precisely regulated

output voltages of 5V, 12V, {12V and {15V.

The -25] 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 82%, continuous short circuit, 60mA output

ripple, built-in filtering for both input and output minimizes the need

for external filtering.

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 90°C.

The derating curves are determined from measurements

obtained in an experimental apparatus.
