LM2853-1.2EVAL Introduction
The LM2853 synchronous SIMPLE SWITCHER® buck regulator is a synchronous switching regulatorcapable of delivering up to 3A of current into a load. The LM2853 represents the ultimate in ease of use,as internal type-3 compensation minimizes the necessary external components and eases the selection ofthose components. The LM2853 is capable of accepting an input voltage between 3.0V and 5.5V anddelivering an output voltage that is factory programmable from 0.8V to 3.3V in 100mV increments. Thenominal switching frequency of the LM2853 is 550 kHz.The LM2853 Evaluation Board was designed to accommodate three standard output voltage options(1.2V/1.8V/3.3V) using the same layout and external components. Just five external components areincluded on the board, and the entire 3A power supply occupies a minimum amount of space (1.2” by0.82”) on a two layer PCB without sacrificing efficiency or performance. The input voltage can be variedover the entire operating range of the LM2853 (3.0V to 5.5V) for testing purposes. Also, the board isdesigned to be stable with all standard LM2853 voltage options, so if another voltage option needs to betested, the LM2853 IC can be removed and replaced with the desired option.
