A7221

AiT Semiconductor Inc. www.ait-ic.com A7221 DC-DC CONVERTER BUCK (STEP-DOWN) 2A, 20V SYNCHRONOUS 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. 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.
