LAS6351 application circuit - high current high efficiency Switching Power Supply circuit

The LAS6351 is a high current adjustable pulse width switching integrated regulator with more complete functions. It can output a voltage range of 2.5~50V under the condition of 3~8A continuous load current; there is soft start, overload overvoltage protection overheat protection switch circuit in the chip; efficiency is up to 90%; since the switching frequency is up to 200kHz, it is reduced The cost of the external output LC filter. It can be used to directly assemble 15W, 25W, 40W adjustable or fixed switching power supply. The circuit shown is a +5V, 5A switching regulator.
