NON-ISOLATED DC/DC CONVERTERS
BP02V7PB-10A
12V Input / 1.0 – 5.0V Output / 10A
• Nonisolated
• Industry standard pinout
• Fixed frequency
• High efficiency means less power dissipation
• Optimized for cost
• Remote on/off
• Remote sense
• Undervoltage lockout
• Over current and short circuit protection
• Overtemperature shutdown
Description
The Bel V7PB-10A series modules are non-isolated, step down DC/DC power conver ters that operate from a nominal 12V
source. These conver ters are available in a range of output voltages from 1.0V to 5.0V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 10A output. Standard features include remote on/off, remote sense,
over current and shor t cicuit protection, over temperature shutdown and output voltage adjust. Remote on/off logic is an
optional feature. These products may be used almost anywhere low-voltage silicon is employed and a 12V source is available.
Typical applications include file ser vers, routers, line cards and other computing and communications equipment.
