illustrate

The LM22678 series of regulators are monolithic integrated circuits that provide buck switching regulators capable of driving excellent line and load regulation characteristics with 5A loads (buck) all the positive functions. High efficiency (> 90%) is achieved by using a low resistance N-channel MOSFET. The series consists of a fixed 5V output and adjustable version.

SIMPLE SWITCHER ® The concept provides an easy-to-use complete design using a minimum number of external components and the WEBENCH of National Semiconductor ® Design tools. WEBENCH of National Semiconductor ® Tools include features such as external component calculations, electrical simulation, thermal simulation, and simple design, build, and board of it. The switching clock frequency is made up of an internal fixed frequency oscillator, which is at 500 kHz. The LM22678 series also features built-in thermal shutdown, current limit, and enable control inputs that can adjust quiescent current standby up and down at 25μA lower power.
