As the picture shows, it is a heavy current and high power switch constant voltage power supply circuit formed by LAS6351. LAS6351 is a kind of switch integrated AVR which has heavy current and adjustable impulse width. It can output 2.5 V to 5 V voltage under 3 A to 8 A constant load current. It has soft boot and over load, over voltage as well as over current protecting circuits. Its efficiency can reach 90%. Because of the 200kHz efficiency, the cost of outer filter is lowered down.
