Analog Devices Inc. EVAL-ADP2441 Board for ADP2441 Step-Down Regulator

Analog Devices Inc. EVAL-ADP2441 Board for ADP2441 Step-Down Regulator is a complete, DC-to-DC switching regulator design based on the ADP2441, a configurable, 1A, synchronous step-down, DC-DC regulator. The EVAL-ADP2441 Board features a 5V at 1A output, with a switching frequency set to 500kHz. The configuration of the EVAL-ADP2441 Board can be modified by changing the values of the appropriate passive components.

Analog Devices ADP2441 is a synchronous, step-down DC-DC switching regulator that uses a current mode Pulse-Width Modulation (PWM) control scheme at medium-to-heavy load currents for high efficiency and smoothly transitions to a pulse skip mode at light loads to conserve power. The power switch and synchronous rectifier are integrated for minimal external part count and high efficiency. The ADP2441 is optimized for operation with small ferrite core inductors and ceramic capacitors to deliver the maximum output power per square millimeter of the PCB board area.
