Analog Devices Inc. ADP2384ACPZN-R7 Synchronous Buck Converter
The ADP2384ACPZN-R7 from Analog Devices Inc. is a high-efficiency, synchronous step-down DC-DC converter designed for demanding power supply applications. Housed in a compact 3mm × 3mm LFCSP-10 package, this IC operates over an input voltage range of 4.5V to 20V, delivering a programmable output voltage from 0.6V to 85% of the input voltage with a maximum continuous output current of 4A. Utilizing a current-mode control architecture at a fixed switching frequency of 1.2MHz (adjustable via external resistor), it achieves high efficiency up to 95% and supports operation across the industrial temperature range (-40°C to +125°C). The device integrates low-RDS(on) MOSFETs (70mΩ high-side, 40mΩ low-side) and features a Power Good indicator for system monitoring.
Key Features of Buck Switching Regulator IC ADP2384ACPZN
The ADP2384ACPZN-R7 excels with its precision reference voltage (±1% accuracy over temperature) and programmable soft-start to minimize inrush current. It incorporates cycle-by-cycle current limiting, hiccup-mode short-circuit protection, and thermal shutdown for robust fault management. The converter supports frequency synchronization to external clocks (600kHz to 1.4MHz) to reduce EMI in noise-sensitive designs. Additional highlights include a low quiescent current (35µA in shutdown mode), adjustable loop compensation, and a lightweight Eco Mode™ for improved light-load efficiency. Its adaptive gate drive technology ensures optimal switching performance across load conditions.
ADP2384ACPZN Applications
This converter is ideal for industrial automation systems, telecom base stations, and distributed power architectures requiring high-density voltage regulation. It serves as a primary power source for FPGAs, ASICs, and processors in embedded computing, medical imaging equipment, and test/measurement instruments. Other applications include 12V/24V bus conversion in automotive infotainment systems, battery-powered IoT gateways, and UAV power management modules.
