FAN6555MX Description

Short technical summary and product information.

The FAN6555MX switching regulator by On Semiconductor is engineered to convert voltage supplies ranging from 2.3V to 4V into desired output or termination voltages for DDR SDRAM memory. This device integrates power MOSFETs and requires minimal external components, eliminating the need for a heatsink.

 

Key electrical specifications include the ability to source and sink up to 2A continuous current, with a 3A peak capability. The output voltage is regulated to within ±3% at 2A. It operates across a temperature range of -40°C to +85°C and features a thermal shutdown protection at approximately 130°C. The FAN6555MX supports both default mode operation (output is 50% of VCCQ) and user-defined voltages via the VREF IN pin.

 

Packaged in a 16-pin SOIC, the FAN6555MX is suitable for surface mount applications. Its design is optimized for active termination schemes in high-speed transmission lines, commonly found in high-speed memory buses and distributed backplane designs. The regulator also includes a shutdown feature for standby or suspend mode operations.
