Technical content

The Bel xRBH -03Hxx0 is a part of the low cost non -isolated DC/DC power converter series providing up to 3 A output current. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. T he output is closely regulated and the efficiency of 3.3 VDC output is typically 88% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection.

• 9 VDC – 36 VDC Input
• 1.2 VDC – 5.0 VDC /3 A Output
• Non-Isolated
• Remote On/Off
• High Efficiency
• Input Under Voltage Lockout
• High Power Density
• OCP/SCP
• Excellent Thermal Performance
• Low Cost
• Class II, Category 2, Isolated DC/DC Converter (refer to IPC-9592B)
