TPA 24V & 48V Series
1W 3KVDC Isolated Single and Dual Output DC/DC Converters
：
DESCRIPTION
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.
