NON-ISOLATED DC/DC CONVERTERS 4.5V-32V Input 1.2V-5.0V/1A Output x7AH-01Hxx0 • • • Non-Isolated Remote On/Off Series • • • OCP/SCP Trim Function Low profile package (7.82mm) Input Under Voltage Lockout (UVLO) Description The Bel x7AH-01Hxx0 series are part of the low cost non-isolated DC/DC converter series. These modules use a SMD or vertical mount package for ease of layout and space savings. The output is closely regulated and the efficiency of 5V output is typically 90% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection.

Output Trim Equations Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal output voltage of the converter (Vo) are shown below. The Trim Down resistor should be connected between the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of the resistors should be used for any given application.
