Description

The Bel SRBC-16E2Ax 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 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 Input Voltage Max. Output Current Max. Output Power Typical Efficiency Model Number Active Low Model Number Active High 0.75 V - 3.63 V 4.5 V - 14 V 16 A 58 W 92% SRBC-16E2AL 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.

SRBC-16E2Ax 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. SRBC-16E2Ax RoHS Compliant Rev.A
