Product Details

The MAX1917 evaluation kit (EV kit) demonstrates the MAX1917's standard 7A application circuit. This DC-DC converter provides a complete power-management solution for DDR memory. This EV kit is a fully assembled and tested circuit board. The MAX1917 EV kit generates a regulated voltage for VTT and VTTR that is half the voltage at the DDR input. The input voltage range is 2.5V to 14V. The circuit is configured to deliver 7A of output current. The DC-DC converter uses buck topology with synchronous rectification to achieve low output voltage with greater than 90% efficiency. The converter output is capable of sourcing and sinking current. Sink capabilities at low voltage arise from the use of a synchronous rectifier, which allows the inductor current to reverse. The EV kit operates at 550kHz switching frequency and has superior load-transient response that meets JEDEC specifications for DDR memory.
