• Nonisolated
• Industry standard footprint
• Fixed frequency
• High efficiency means less power dissipation
• Excellent thermal performance
• Optimized for cost
• Remote on/off
• Remote sense
• Undervoltage lockout (UVLO)
• Over current and short circuit protection
• Industrial temperature range
Description
The Bel V7PB-10C modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal
3.3V source. These converters are available in a range of output voltages from 0.9V to 2.5V. They are packaged in a compact,
SIP package rated at 10A. Standard features include remote on/off, over current and short circuit protection, output voltage
adjust and industrial temperature range (-40° to +85° C). The output is closely regulated and the efficiency is typically 95% @
2.5V output at full load. These products may be used almost anywhere low voltage silicon is employed and a 3.3V source is
available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
Applications
• Distributed power architectures
• Data networking equipment
• Telecommunications
• Computers and peripherals
