A7406

AiT Semiconductor Inc. www.ait-ic.com A7406 DC-DC CONVERTER/BUCK (STEP-DOWN) 600mA, 40V SYNCHRONOUS STEP-DOWN CONVERTER DESCRIPTION FEATURES The A7406 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the A7406 delivers 600mA of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit.        The A7406 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.    4.7V to 40V operating input range 600mA output current Up to 93% efficiency High efficiency (>78%) at light load Internal Soft-Start 2MHz switching frequ...
