La familia UCC28C4x de controladores PWM de modo de corriente de alto rendimiento. Son una versión mejorada de BiCMOS pin pin compatible con la familia UC284xA estándar de la industria y la familia UC284x de controladores PWM. Además, una versión con un voltaje de arranque más bajo de 7 está disponible como UCC28C41.
Al proporcionar las funciones necesarias para controlar fuentes de alimentación de frecuencia fija y modo de corriente máxima, la serie ofrece una variedad de beneficios de rendimiento. Estos dispositivos proporcionan altas frecuencias de funcionamiento hasta un bajo arranque y corriente de funcionamiento de megahercios, lo que reduce el arranque para mejorar la eficiencia, las bajas pérdidas y el bajo consumo de energía operativa. Estos dispositivos también cuentan con un tiempo de retardo de detección a salida de corriente rápida de 35 nanosegundos, un aumento máximo de salida de ± 1 y un tiempo de lluvia radiactiva mejorado para que los MOSFET externos impulsen grandes corrientes directamente.
