Description
The Bel xRPF-20A1Ax is a new high density open frame non-isolated converter series for space sensitive
applications. Each model has a wide input range (10.2 Vdc - 13.8 Vdc) and offers a wide range of output voltage
(0.9 Vdc - 5.0 Vdc) with a 20 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9
Vdc to any value up to the 5.0 Vdc maximum. Typical efficiency is 92% at Vo=5 Vdc, Vin=12 Vdc at full load.
Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection.

Notes:
1. Add “G” suffix at the end of the model number to indicate Tray Packaging.
2. “B” suffix version has both a filtered Power Good signal and the ability to have a Power Good signal
pull up as low as 0.9 V (lowest programmable output voltage).
3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
