NON-ISOLATED DC/DC CONVERTERS Vdc - Vdc Input Vdc - Vdc/3 A Output xRAH-03F1A0 • Non-Isolated • High Efficiency • Fixed Frequency 300 kHz • Low Cost • UL60950-1 Recognized UL/cUL • Remote On/Off • Input Under Voltage Lockout • OCP/SCP • Wide Range Trim The Bel xRAH-03F1A0 module is a non-isolated, step down dc/dc converter that operates from Vdc to Vdc source. This converter is available in a range of output voltages from Vdc to Vdc. It is packaged in a compact, overmolded package rated at 3 A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The efficiency of Vdc module is typically 92% at 5 Vdc input and full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection.
