DESCRIPTION
The AT7200 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~18V, the AT7200 delivers 2A 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 ripples. Current mode control provides tight loa.
