Description

General part information

ADP2390 Series

The ADP2389/ADP2390 are current mode control, synchronous step-down, dc-to-dc regulators. They integrate a 17 mΩ high-side power MOSFET and a 4.5 mΩ synchronous rectifier MOSFET to provide a high efficiency solution. The ADP2390 operates in pulse frequency modulation (PFM) mode to improve the system efficiency at light load. The ADP2389/ADP2390 run from an input voltage of 4.5 V to 18 V and can deliver up to 12 A of output current. The output voltage can be adjusted to 0.6 V and the switching frequency can be programmed between 200 kHz to 2200 kHz.The ADP2389/ADP2390 target high performance applications that require high efficiency and design flexibility. External compensation and soft start provide design flexibility. The power-good output and precision enable input provide simple and reliable power sequencing. An enhanced transient response feature improves the load transient performance, which reduces the output capacitance. Programmable current limit allows the user to optimized the inductor design and provide a compact solution.Other key features include undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).The ADP2389/ADP2390 operates over a .40‹C to +125°C junction temperature range and is available in 32-lead, 5 mm ~ 5 mm LFCSP package.ApplicationsCommunication infrastructureNetworking and serversIndustrial and instrumentationHealthcare and medicalIntermediate power rail conversionsDC-to-DC point of load applications
