NON-ISOLATED DC/DC CONVERTERS 4.5V-13.2V Input 0.9V-5.0V/3A Output x7AH-03Exx0 Series • Non-Isolated • Low Cost • High Efficiency • Remote On/Off • High Power Density • Under-voltage Lockout (UVLO) * • Excellent Thermal Performance • OCP/SCP * Not applicable for 5.0V output module. Description The Bel x7AH-03Exx0 Series are part of the low cost non-isolated DC/DC power converters. The modules use a surface mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82mm. The output is closely regulated and the efficiency of 5V output module is typically 95% at full load. Typical features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection.
