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. Absolute Maximum Ratings Parameter Input Voltage (continuous) Output Enable Terminal Voltage Sequencing Voltage 1 Min -0.3 V -0.3 V -0.3 V -40 C -55 C Typ - Max 15 V 15 V Vin 85 C 125 C Notes Ambient Temperature Storage Temperature Notes: All specifications are typical at 25 C unless otherwise stated. 1. VRBC-16A2Ax series of modules include a sequencing feature that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, either, tie the SEQ pin to Vin or leave it unconnected.
