A7221 Overview
The A7221 is a current mode monolithic buck voltage converter. Operating with an input range of 4.7V~20V, the A7221 delivers 2A of continuous output current with two integrated N-Channel MOSFETs. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple.
