NON-ISOLATED DC/DC CONVERTERS

4.5 Vdc - 13.2 Vdc Input 1.0 Vdc - 5.0 Vdc/6 A Output

xRAH-06Exx0 Series RoHS Compliant Rev.A

• Non-Isolated • OCP/SCP (Latch off)

• Fixed Frequency (400 kHz) • Trim Function

• Remote On/Off • Low Profile Package (7.82 mm)

• Under-voltage Lockout (UVLO) • UL60950-1 Recognized (UL/cUL)

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.
