MSKUW Series

5 Watt DC/DC Converter

Single and Dual Outputs

Rev A

4:1 Ultra Wide Input Voltage Range

FEATURES

DESCRIPTION

● SMT Technology

The MSKUW series of DC/DC converters provide a maximum of 5 watts in a “gull-wing” SMT

package. These converters operate over 4:1 ultra wide input voltage ranges of 9-36 or

18-75VDC. 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 83%, remote ON/OFF control, 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,

● High Power Density

● Efficiency up to 83%

● 1500VDC I/O Isolation

● Short Circuit Protection

● Remote ON/OFF Control

● MTBF > 1,000,000 Hours

● 4:1 Ultra Wide Input Voltage Range

● EMI Complies with EN55022 Class A

telecommunication equipment, computer peripheral systems, distributed power systems, mixed analog/digital

subsystems, and industrial robot systems. The EN55022 Class A conducted noise compliance minimizes

● Operating Temperature: -40°C to +71°C design time, cost, and eliminates the need for external filter components.

SPECIFICATIONS: MSKUW 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.
