ADP2107ACPZ-R7

ADP2107 is a low quiescent current, synchronous, step-down DC to DC converter. At medium to high load currents, this device uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, this device use a pulse frequency modulation (PFM) control scheme under light load conditions that reduces switching frequency to save power. This device run from input voltages of 2.7V to 5.5V, allowing single Li+/Li− polymer cell, multiple alkaline/NiMH cells, PCMCIA, and other standard power sources. It is widely used in application such as mobile handsets, PDAs and palmtop computers, telecommunication/networking equipment, set top boxes, audio/video consumer electronics etc.
