Description
The Bel VRBC-10E1Ax is part of the non-isolate dc/dc power converter series. The modules use a SIP package.
These converters are available in a range of output voltages from 0.75 Vdc to 3.63 Vdc over a wide range of input
voltage (Vin = 4.5 Vdc - 14 Vdc). The efficiency is typically 94.3% at 3.3 Vdc output at 5.0 Vdc input at full load.

Notes
An input line fuse must always be used.
Tested with one 1000 uF/25V AL input
capacitor with ESR=0.03ohm max and
4 × 47 uF/16V Tantalum capacitors
with ESR=0.013 ohm max at 100 kHz,
& simulated source impedance of
1000nH, 5 Hz to 20MHz.
