NON-ISOLATED DC/DC CONVERTERS 4.5V-32V Input x7AH-01Hxx0 1.2V-5.0V/1A Output Series • Non-Isolated • OCP/SCP • Remote On/Off • Trim Function • Input Under Voltage Lockout (UVLO) • Low profile package (7.82mm) 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. Part Selection Output Voltage 5.0V Input Voltage 8.0 – 32V Max. Output Current 1A Max.
