Description
The Bel VRAE-03E1AC is part of the non-isolated dc/dc converter Power Module series. The modules use a SIP
package. These converters are available in a range of output voltages from 0.59 Vdc to 5.1 Vdc over a wide
range of input voltage (VIN = 4.5 Vdc - 13.8 Vdc).The efficiency is typically 91% at 3.3 Vout (Vin=12 Vdc) at full
load.

Notes
An input line fuse must always be used.
With simulated source impedance of
1000 nH, 5 Hz to 20 MHz. Use a 1000
uF/25 V AL-Cap with ESR=0.03 ohm
max and 2*100 Uf/25V Tan-Cap with
ESR=0.013 ohm max at 100
kHz@25°C.
A 30.1K resistor is connected from
Enable to Vin.
