i6A4W Series
250W, 9-53V Input
Non-isolated DC-DC Converters
i6A4W Series
1
Features Benefi ts
The i6A 4W series of non-isolated step-down converters are ideal for creating additional high current output voltages from a single output 12V, 24V or 48V
AC-DC power supply. The highly effi cient i6A 4W series accepts a very wide DC input and has a wide output adjustment range, with a choice of 1/16th brick
footprint or SIP package.
• Up to 250W in a 1/16th brick or SIP package
• Very high Effi ciency up to 97%
• Wide Output Adjustment 3.3 to 15V & 3.3 to 40V
• Minimal External Components Needed
• Low Airfl ow With Minimal Derating Requirements
• Very High Power Density
• Easier Thermal Management
• One Part For Multiple Applications
• Less Board Area Required
• Easier To Cool In End System
