La serie LM22679 de reguladores son circuitos integrados monolíticos que proporcionan reguladores de conmutación reductora capaces de impulsar excelentes características de regulación de línea y carga con cargas de 5A (buck) todas las funciones positivas. 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. La serie LM22679 también tiene apagado térmico incorporado y limitación de corriente. An external resistor can be used to adjust the current limit threshold. An adjustable soft-start function is achieved by selecting the appropriate external soft-start capacitor.
