RT8267 2A, 22V, 400kHz Step-Down Converter
●General Description
■The RT8267 is an asynchronous high voltage buck converter that can support the input voltage range from 4.75V to 22V and the output current can be up to 2A. Current Mode operation provides fast transient response and eases loop stabilization.
■The chip provides protection functions such as cycle-by-cycle current limiting and thermal shutdown protection.In shutdown mode, the regulator draws 25μA of supplyc urrent. The RT8267 is available in a SOP-8 surface mount package.
●Features
■Wide Operating Input Range : 4.75V to 22V
■Adjustable Output Voltage Range : 1.222V to 16V
