ADP2380It is a current mode control, synchronous,Step-down DC/DC regulatorA 44 mΩ high-side power MOSFET and a low-side driver are integrated to provide a high efficiency solution. The ADP2380 operates from an input voltage of 4.5 V to 20 V and can deliver 4 A of output current. The output voltage is adjustable from 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 adjustable soft-start provide design flexibility. The power good output provides simple and reliable power sequencing. Other features include programmable undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).
The ADP2380 operates over the junction temperature range of -40°C to +125°C and is available in a 16-lead TSSOP_EP package.
