RT2658
Description
The RT2658 in thermally enhanced VQFN-20L 3.5x4 package is a full featured 6V, 6A synchronous step-down DC-DC converter designed specifically for Double Data Rate (DDR) memory termination, which provides a continuous 6A sink and source current and fixed 1/2 DDQ at output. The current mode COT architecture with external compensation allows the transient response to be optimized over a wide range of loads and achieves nearly constant switching frequency over line, load, and output voltage ranges.
