GENERAL DESCRIPTION

The ADP2381 is a current mode control, synchronous, step down, dc-to-dc regulator. It integrates a 44 mΩ power MOSFET and a low-side driver to provide a high efficiency solution. The ADP2381 runs from an input voltage of 4.5 V to 20 V and can deliver 6 A of output current. The output voltage can be adjusted to 0.6 V to 90 of the input voltage. The switching frequency of the ADP2381 can be programmed from 250 kHz to 1.4 MHz or fixed at 290 kHz or 550 kHz.
