A7221 Description
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.
A7221 Key Features
- 4.7V to 20V operating input range 2A output current
- Up to 95% efficiency
