Abstract

Se describe un circuito de control de carga, tal como un accionador (LED) de diodo emisor de luz, para controlar la cantidad de energía entregada a una carga eléctrica, que comprende un transistor de regulación adaptado para ser acoplado en serie con la carga, y un circuito de retroalimentación acoplado en serie con el transistor de regulación, con lo cual el circuito de control de carga es capaz de controlar la magnitud de un corriente de carga conducida a través de la carga desde una corriente de carga mínima a una corriente de carga máxima, que es al menos aproximadamente mil veces mayor que la corriente de carga mínima. El circuito de retroalimentación genera al menos una señal de retroalimentación de corriente de carga que es representativa de la magnitud de la corriente de carga. El transistor opera en la región lineal para controlar la magnitud de la corriente de carga conducida a través de la carga en respuesta a la magnitud de la corriente de carga determinada desde la señal de retroalimentación de corriente de carga.
