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 Voltage 0.75 V - 5.0 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 SRBC-16A2AL Model Number Active High SRBC-16A2A0 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.

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.
