SRBH-06H1A1G Bel Fuse

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. Key Features & Benefits 8-36 VDC Input / 3.3-5 VDC 6 A Output Non-isolated output High Efficiency High Power Density Excellent Thermal Performance OCP/SCP Remote On/Off Input Under Voltage Lockout Low Cost Class 2, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592B) Applications Distributed Power Architectures Data Networking Equipment Telecommunications Applications belpowersolutions.com 2 SRBH-06H1A1 1.
