A7221 - DC-DC CONVERTER BUCK

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.

Features

  • 4.7V to 20V operating input range 2A output current.
  • Up to 95% efficiency.
  • High efficiency (>80%) at light load.
  • Fixed 500kHz Switching frequenc.

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. The A7221 guarantees robustness with over current protection, thermal protection, start-up current run-away protection, and input under voltage lockout. The A7221 is available in TSOT-26 package.
