These modules provide precisely regulated voltage programmable via external resistor from 0.75 Vdc to 5.0 Vdc over a wide range of input voltage (8.3 Vdc - 14 Vdc). These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. The open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, remote sense, over current protection, short current protection, wide input, and programmable output voltage. ## **Part Selection** |**Output**

SRBC-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 the sequencing feature is not used, tie the SEQ pin to Vin or leave it unconnected. **Bel Fuse Inc.** 206 Van Vorst Street, Jersey City, NJ 07302 • Tel 201-432-0463 • Fax 201-432-9542 • www.belfuse.com ## **NON-ISOLATED DC/DC CONVERTERS 8.3 Vdc - 14 Vdc Input 0.75 Vdc - 5.0 Vdc/16 A Output** ee ## **Input Specifications** |**Parameter **|**Min**|**Typ**|**Max **|**Notes**| |---|---|---|---|---| |Input Voltage
