一、DESCRIPTION
The are monolithic buck switching regulator based on I2 architecture for fast transient response. Operating with an input range of 4.5V~18V, deliver 3A 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, operate in low frequency to maintain high efficiency. guarantee robustness with output short protection, thermal protection, current run-away protection and input under voltage lockout. are available in SOT23-6 package, which provide a compact solution with minimal external components.
