JW5068A 23V/8A Sync. Step-Down Converter Preliminary Specifications Subject to Change without Notice DESCRIPTION FEATURES The JW ®5068A is a monolithic buck switching regulator based on I2 architecture for fast transient response. Operating with an input range of 4V~23V, JW5068A delivers 8A 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.  JW5068A guarantees robustness with output short protection, thermal protection, current run-away protection, and input under voltage lockout.  JW5068A is available in QFN3X3-20 package, which provide a compact solution with minimal external components.
