Maxim Integrated Products introduces the DS4422/DS4424 low-cost, dual-/quad-channel, sink/source current DACs. These I²C-controlled, 7-bit current DACs feature two (DS4422)/four (DS4424) output channels that are specifically designed for power-supply margining and adjustment. Each output channel provides control of a DC-DC power supply by sinking or sourcing current directly into the power supply's feedback node. This control technique allows existing power-supply designs to be margined and adjusted with minimal redesign, thus making the DS4422/DS4424 ideal for servers, video processing cards, and other DC-DC power-supply applications. |
