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 Bel SRBC-16E2Ax 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 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-16E2AL Model Number Active High SRBC-16E2A0 Notes: 1. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers. 2. Add “G” suffix at the end of the model number to indicate Tray Packaging.
