The ADP2386 is a synchronous step-down， dc-to-dc regulator with an integrated 44 mΩ， high-side power MOSFET and an 11 mΩ， synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm × 4 mm LFCSP package. This device uses a peak current mode， constant frequency pulse-width modulation （PWM） control scheme for excellent stability and transient response. The switching frequency of the ADP2386 can be programmed from 200 kHz to 1.4 MHz. To minimize system noise， the synchronization function allows the switching frequency to be synchronized to an external clock. The ADP2386 requires minimal external components and operates from an input voltage of 4.5 V to 20 V. The output voltage can be adjusted from 0.6 V to 90% of the input voltage and delivers up to 6 A of continuous current. Each IC draws less than 110 μA current from the input source when it is disabled. This regulator targets high performance applications that require high efficiency and design flexibility. External compensation and an adjustable soft start function provide design flexibility. The powergood output and precision enable input provide simple and reliable power sequencing.
