Description

The Bel x7AH-05BT50 is part of the low cost non-isolated DC/DC converter series. The converter is designed

specifically to provide bus termination voltage in application such as DDR (double data rate) memory where the

bus termination voltage must closely track the I/O bus voltage. The converter accepts a reference input and

programs its output voltage to 50% of the reference. The modules use a SMD or vertical mount package for

ease of layout and space savings.
