ADI ADP2386ACPZN-R7

The ADP2386 is a synchronous step-down DC-DC regulator integrating a 44 mΩ high-side power MOSFET and an 11 mΩ synchronous rectification MOSFET in a compact 4 mm×4 mm LFCSP package, delivering a high-efficiency solution. The device employs a peak current mode, constant-frequency PWM control scheme, offering excellent stability and transient response. The ADP2386 switching frequency is programmable from 200 kHz to 1.4 MHz. To minimize system noise, a synchronization feature allows the switching frequency to be synchronized with an external clock. The ADP2386 requires minimal external components, with an input voltage range of 4.5 V to 20 V. The output voltage is adjustable from 0.6 V to 90% of the input voltage, delivering up to 6 A of continuous current. The IC draws less than 110 μA from the input source when disabled. The regulator targets high-performance applications requiring high efficiency and design flexibility. External compensation and adjustable soft-start provide design flexibility. Power good output and precision enable input offer simple, reliable power sequencing. Additional key features include UVLO, OVP, OCP, SCP, and TSD. The ADP2386 operates over a junction temperature range of -40°C to +125°C in a 24-lead 4 mm×4 mm LFCSP package.
