Микросхемы и комплектующие DC1588A

The DC1588A demonstration board features LTM4611EV DC to DC µModule Regulator. The LTM4611EV is a high density 15A output, switch mode DC to DC buck converter power supply capable of operating from very low voltage input supplies. Included in the IC package are the buck switching controller, power FETs, inductor and loop compensation components. The operating input voltage range is 1.5V to 5.5V with an output voltage range from 0.8V to 5V. The DC1588A can support a load current up to 15A, while derating may be necessary for different VIN, VOUT and thermal conditions. The board has a default programmable switching frequency of 500KHz and may be synchronized to an external clock from 360KHz up to 710KHz. The TRACK/SS input allows the output voltage to ramp up and ramp down, coincidentally or ratiometrically with an external voltage. A remote output voltage sense feature improves the output voltage accuracy under high loads.
