• Remote On/Off
• Short circuit protection
• Over current protection
• Trim Function
Description
The Bel xRAH-10Jxx0 is part of the low cost non-isolated dc/dc power converter series. The modules use a
SMD or SIP package for ease of layout and space savings. The output is closely regulated and the efficiency of
1.5 V output is typically 88% at full load. Typical features include remote on/off, input under voltage lockout,
over current protection and short circuit protection.
