Analog Devices, Inc. 20 V, 6 A Synchronous Step-Down Regulator with Low-Side Driver ADP2381AREZ

Description
Product Details 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. 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 ADP2381 operates over the −40°C to +125°C junction temperature range and is available in a 16-lead TSSOP_EP package.
