DESCRIPTION
The MSKW series of DC/DC converters provide a maximum of 5 watts in a
“gull-wing” SMT package. These converters operate over 2:1 wide input
voltage ranges of 9-18, 18-36, or 36-75VDC. This series also has single
output voltages of 3.3, 5, 12, and 15VDC and dual output voltages of ±5,
±12, and ±15VDC. These converters have a typical full load efficiency of
85%, remote ON/OFF, and continuous short circuit protection. The
-40°C~+71°C operating temperature make these converters ideal for data
communication equipment, mobile battery driven equipment, process/machine
control equipment, telecommunication equipment, computer peripheral systems,
distributed power systems, mixed analog/digital subsystems, and industrial robot systems. The
EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need
for external filter components.
SPECIFICATIONS: MSKW Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.
We reserve the right to change specifications based on technological advances.
