DC/DC Converters
TMA Series, 1 Watt
Features
◆ Single-in-line (SIP) package
◆ Single and dual output models
◆ I/O isolation 1‘000 VDC
◆ Unregulated device
◆ High efficiency up to 81%
◆ Operating temp. range –40°C to +85°C
◆ Industry standard pinout
◆ 100% Burn-in (8 h)
◆ Lead free design, RoHS compliant
◆ 3-year product warranty The TMA series are miniature, isolated 1 W DC/DC-converters in a Single-in-Line
package (SIP). Requiring only 1.2 cm2 board space they offer the ideal solution in
many space critical applications for board level power distribution. The use of SMD-
technology makes it possible to offer a product with high performance at low cost.
