illustrate

El microcontrolador de la serie LM22680 del regulador proporciona un regulador de conmutación de acción activa (buck) para conducir hasta 2A con excelentes características de regulación de línea y carga para todos los circuitos integrados. High efficiency ("90%) is achieved through the use of N-channel MOSFETs with low resistance.

In simple switches ® The concept provides an easy-to-use complete design using a minimum number of external components and state the WEBENCH ® Design tools. WEBENCH of National Semiconductor ® Tools include functions for external component calculation, electrical simulation, thermal simulation, etc., and build-IT boards for easy design. The clock switching frequency is made up of an internal fixed frequency oscillator that operates at 500 kHz. La frecuencia de conmutación también se puede ajustar o sincronizar a un reloj externo de hasta 1 MHz con una resistencia externa. También puede sincronizar automáticamente las operaciones con múltiples organismos reguladores que comparten la misma frecuencia de conmutación. La serie LM22680 también cuenta con apagado térmico incorporado, límite de corriente y permite entradas de control que pueden apagar el regulador de potencia en un estado de espera de corriente de reposo de 25 μA. An adjustable soft-start function provides the selection of an appropriate external soft-start capacitor.
