NON-ISOLATED DC/DC CONVERTERS 4.5 Vdc - 14 Vdc Input 0.75 Vdc - 3.63 Vdc/16 A Output SRBC-16E1Ax RoHS Compliant Rev.A Non-Isolated High Efficiency Fixed Frequency Low Cost Over Temperature Shutdown Logic Low/High (option) Industrial Temperature Range Under-voltage Lockout (UVLO) OCP/SCP Wide Trim Wide Input Remote Sense Remote On/Off Description The Bel SRBC-16E1Ax is part of the non-isolated dc/dc converter series. The modules use a SMT 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 92% at 3.3 Vdc output at full load. Part Selection Output Voltage 0.75 V - 3.63 V Input Voltage 4.5 V -14 V Max. Output Current 16 A Max. Output Power 58 W Typical Efficiency 92% Model Number Active Low SRBC-16E1AL Model Number Active High SRBC-16E1A0 Notes: 1. Add “G” suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
