Description

The Bel SRBC-16F1Ax modules are a series of non-isolated dc/dc converters that deliver up to 16 A of output

current with full load efficiency of 94% at 3.3 Vdc output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 Vdc to 3.63 Vdc over a wide range of input voltage (Vin=2.4 Vdc -

5.5 Vdc). The open-frame construction and small footprint enable designers to develop cost and space-efficient

solutions. Standard features include remote On/Off, over current protection, short current protection, wide input,

and programmable output voltage.
