Scope measurement should be made by using a BNC socket, measurement bandwidth 0-20MHz. Position the load between 50mm and 75mm from the DC/DC converter. TECHNICAL NOTES 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 3.3µF capacitors at the output. Maximum Capacitive Load The DCMAR05 series has limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and the startup time. Maximum capacitance can be found in the data sheet. 5/22/2017 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 3 of 4 Rev A DCMAR05 SERIES 0.5A DC/DC Switching Regulator Single Outputs COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
