Analog Devices ADP2384
The ADP2384 is a synchronous, step-down dc-to-dc regulator with an integrated 44 mΩ, high-side power MOSFET and an 11.6 mΩ, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm × 4 mm LFCSP package. This device uses a peak current mode, constant frequency pulsewidth modulation (PWM) control scheme for excellent stability and transient response. The switching frequency of the ADP2384 can be programmed from 200 kHz to 1.4 MHz.| Part No. | ADP2384 |

Communications infrastructure Networking and servers Industrial and instrumentation Healthcare and medical Intermediate power rail conversion DC-to-dc point-of-load applicationsGENERAL DESCRIPTION
To minimize system noise, the synchronization function allows the switching frequency to be synchronized to an external clock. The ADP2384 requires minimal external components and operates from an input voltage of 4.5 V to 20 V. The output voltage can be adjusted from 0.6 V to 90% of the input voltage and delivers up to 4 A of continuous current.
