The modules use a SIP package. These converters are available in a range of output voltages from 0.75 Vdc to 5.5 Vdc over a wide range of input voltage (Vin = 8.3 Vdc - 14 Vdc). The Bel VRBC-16A2Ax has a sequencing feature that enables designers to implement various types of output voltage sequencing when powering. The efficiency is typically 92% at 3.3 Vdc output and 12 Vdc input at full load. Part Selection Output Voltage 0.75 V - 5.5 V Input Voltage 8.3 V - 14 V Max. Output Current 16 A Max. Output Power 80 W Typical Efficiency 94% Model Number Active Low VRBC-16A2AL Model Number Active High VRBC-16A2A0 Notes: 1.Change the last character to “C” to indicate 0.20’’ pin length and active low. 2. Add “G” suffix at the end of the model number to indicate Tray Packaging. 3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
