SRBH-06H1A1
Non-Isolated DC-DC Converter
The SRBH-06H1A1 is part of the low cost non-isolated dc/dc
power converter series providing up to 6A output current.
The output is closely regulated and the efficiency of 3.3Vdc
output is typically 89% at full load.
Typical features include remote on/off, input under voltage
lockout, over current protection and short circuit protection.
