The ADP2107ACPZ-R7 from Analog Devices is a synchronous, step-down DC-to-DC converter designed for efficient power management in portable applications. It offers a maximum load current of 2A and operates from an input voltage range of 2.7V to 5.5V, making it suitable for single Li+/Li- polymer cells or multiple alkaline/NiMH cells.
This converter utilizes a current mode, constant frequency pulse-width modulation (PWM) control scheme for stable performance at medium to high load currents. Under light load conditions, it switches to a pulse frequency modulation (PFM) scheme to reduce switching frequency and conserve power, achieving ultralow quiescent current of 20 μA. The output voltage is adjustable from 0.8V to the input voltage (VIN).
Key features include a high efficiency of up to 97%, a switching frequency of 1.2 MHz, and a low shutdown supply current of 0.1 μA. The device is housed in a compact 16-lead 4 mm × 4 mm LFCSP package, optimized for small ceramic output capacitors. It also includes undervoltage lockout and programmable soft start functionalities.
Applications for the ADP2107ACPZ-R7 include mobile handsets, PDAs, telecommunication equipment, set-top boxes, and audio/video consumer electronics where efficient and compact power conversion is required.
