| NON-ISOLATED DC/DC CONVERTERS 4.5 Vdc - 13.2 Vdc Input 1.0 Vdc - 5.0 Vdc/6 A Output XRAH-06EXX0 Series * * * * Non-Isolated Fixed Frequency (400 kHz) Remote On/Off RoHS Compliant * * * * Trim Function Rev.A OCP/SCP (Latch off) Low Profile Package (7.82 mm) UL60950-1 Recognized (UL/cUL) Under-voltage Lockout (UVLO) Description The Bel XRAH-06EXX0 is part of the low cost non-isolated dc/dc converter series. The modules use a surface mount package or vertical package for ease of layout and space savings, with a low profile of only 7.82 mm. The output is closely regulated and the efficiency of 3.3 Vdc output module is typically 91% at full load. Typical features include Remote On/Off, under-voltage lockout, over-current protection and short circuit protection.
