NON-ISOLATED DC/DC CONVERTERS
2.5V Input 0.9V-1.65V/10A Output
x7AH-10J Series
• Non-Isolated
• Low profile package (7.82mm)
• Fixed frequency (300KHz)
• Under-voltage lockout (UVLO)
• Remote On/Off
• Short circuit protection
• Over current protection
• Trim Function
Description
The Bel x7AH-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
1.5V output is typically 88% at full load. Typical features include remote on/off, input under voltage lockout, over
current protection and short circuit protection.
