ADP2384ACPZN-R7

The ADP2384 is a synchronous step-down DC-DC regulator integrating a 44 mΩ high-side power MOSFET and an 11.6 mΩ synchronous rectifier MOSFET in a compact 4 mm × 4 mm LFCSP, delivering a high-efficiency solution. The device employs a peak current mode, constant-frequency PWM control scheme for excellent stability and transient response. Switching frequency is programmable from 200 kHz to 1.4 MHz, and a synchronization feature allows the switching frequency to lock to an external clock to minimize system noise. With minimal external components, the input voltage range spans 4.5 V to 20 V, the output voltage is adjustable from 0.6 V to 90% of the input voltage, and up to 4 A of continuous current is provided. The IC draws less than 120 μA from the input supply when disabled. The regulator targets high-performance applications requiring high efficiency and design flexibility. External compensation and adjustable soft-start provide design flexibility. A power-good output and precision enable input enable simple, reliable power sequencing. Additional key features include UVLO, OVP, OCP, SCP, and TSD. Operating junction temperature range: -40°C to +125°C.
