illustrate

Integrado con un interruptor de alimentación de 1A, el LM3405 es un regulador reductor de conmutación controlado por modo de corriente diseñado como una solución simple y eficiente para controlar LED de alta potencia. Con control de retroalimentación de voltaje de referencia de 0.205V para minimizar la disipación de energía, las resistencias externas configuran la corriente para impulsar el LED para diversas necesidades. La frecuencia de conmutación se ajusta internamente a 1,6 MHz, lo que permite el uso de pequeños inductores y condensadores de montaje en superficie. El LM3405 utiliza control de modo de corriente y compensación interna para el uso y, como era de esperar, proporciona mitigación de regulación de alto rendimiento en una amplia gama de condiciones de funcionamiento. Otras características incluyen LED habilitado y PWM, apagado térmico, limitación de corriente ciclo por ciclo y protección contra sobrecorriente con pines EN/DIM de atenuación accesibles para el usuario.
