DC3131D

DESCRIPTION

    DC3131D has an optimum input voltage, step-down converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. The maximum input voltage is up to 36V and the operation input voltage from 7V to 32V.

MOSFET what build in 35mΩ High-Side and 25mΩ Low-Side, could deliver up to 3.5A of continuous output current and the output current accurate is within ±7%.

No external compensation component requirement. The line compensation and the constant current can be set by an external resistance.

In conclusion,DC3131D is a full function and high performance, high reliability buck DC-DC converter.
