Additional Details

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.

External compensation and an adjustable soft start provide design flexibility. The power-good output provides simple and reliable power sequencing. Additional features include programmable undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).

The ADP2380 operates over the −40°C to +125°C junction temperature range and is available in a 16-lead TSSOP_EP package.

Product Detail

The ADP2380/ADP2381 evaluation board is a complete, 4 A/6 A, 20 V, step-down regulator solution that allows users to evaluate the performance of the ADP2380 and the ADP2381 with a nearly ideal printed circuit board (PCB) layout.

The switching frequency can be programmed between 250 kHz and 1.4 MHz, or it can be synchronized to an external clock with a 180° phase shift, which provides the possibility for a stackable, multiphase power solution.

The output of the ADP2380/ADP2381 evaluation board is preset to 3.3 V, and the switching frequency is set to 500 kHz. Different output voltage settings can be achieved by changing the appropriate passive components. The ambient temperature operating range is −40°C to +85°C.

Full details about the ADP2380 and ADP2381 regulators are provided in the ADP2380 and ADP2381 data sheets, which are available from Analog Devices, Inc. The data sheets should be consulted in conjunction with this user guide.
