GENERAL DESCRIPTION  
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 operates over a −40°C to +125°C  
junction temperature range and is available in 32-lead, 5 mm ×  
5 mm LFCSP package.

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.
