TPA2 Datasheet, PDF (1/3 Pages) Toppower Electronic Technology Limited – 1W Isolated Single and Dual Output DC/DC Converters

TPA 24V & 48V Series
DESCRIPTION： 1W Isolated Single and Dual Output DC/DC Converters
The TPA series are miniature, isolated 1W DC/DC converters in a SIP and DIP
package. They offer the ideal solution in many space critical applications for board level
power distribution. The internal SMD construction makes it possible to offer a product
with high performance at low cost. The series offers smaller size, improved efficiency,
lower output ripple noise and 3KVDC isolation.
