DC/DC Converter
TSM Series, 1 Watt
• SMD package (SOIC-8/10)
• Construction in lead frame technology
• I/O isolation 1000 VDC
• Efficiency up to 82 %
• Operating temperature –40°C to +85°C
• Reflow solder temperature up to 245°C • High accuracy of Pin coplanarity • Available in tape and reel package • 3-years product warranty
The TSM series are isolated DC/DC converters with 1W output power implemented in a molded plastic package with a pin accuracy suitable for automated SMD-production. The devices can be soldered without any problems in a high temperature lead free solder process. With their small footprint these converters are the economical solution for point of load power conversion, ground loop elimination, noise reduction and digital interface applications.
