GENERAL DESCRIPTION
The ADP2380 is a current mode control, synchronous, step-down, dc-to-dc regulator. It integrates a 44 mΩ high-side power MOSFET and a low-side driver to provide a high efficiency solution. The ADP2380 runs from an input voltage of 4.5 V to 20 V and can deliver 4 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 ADP2380 can be programmed from 250 kHz to 1.4 MHz or fixed at 290 kHz or 540 kHz. The synchronization function allows the switching frequency to be synchronized to an external clock to minimize system noise.
