Con una frecuencia de conmutación fija de 150 kHz, utiliza un transistor bipolar NPN interno de 3A con límite de corriente ciclo a ciclo y apagado térmico. La versión de salida fija de 5.0V requiere solo cuatro componentes externos: un condensador electrolítico de desacoplo de entrada, un diodo Schottky rápido, un inductor de potencia y un condensador de filtro de salida. La frecuencia de 150 kHz permite emplear componentes de filtrado notablemente más pequeños que los reguladores de 52 kHz como el LM2576. El bucle de control interno compara el voltaje de salida del pin 4 (FEEDBACK) con una referencia bandgap de 1.23V mediante un divisor resistivo, modulando dinámicamente el ciclo de trabajo para mantener una rigurosa regulación frente a variaciones de 7V a 40V CC.","### 1. Desacoplo de entrada y compensación de carga\nDurante cada ciclo de conmutación, el interruptor bipolar NPN de lado alto dentro de U1 conmuta a 150 kHz, demandando pulsos de corriente trapezoidales de gran amplitud directamente del riel de CC. El condensador de entrada C1 (electrolítico de 680 µF \u002F 50V de bajo ESR) suministra localmente estas corrientes de rizado RMS de alta frecuencia, evitando que los transitorios de conmutación se propaguen hacia la fuente de alimentación. El voltaje de entrada debe mantenerse por encima de 7.0V para conservar la regulación considerando la caída de saturación interna ($V_{SAT} \\approx 1.16\\text{V}$).\n\n### 2. Conducción del interruptor principal y magnetización del inductor\nCuando el oscilador interno inicia un período de reloj, el comparador PWM satura el interruptor bipolar NPN interno de 3A entre el Pin 1 (VIN) y el Pin 2 (OUTPUT). La tensión en el nodo de conmutación sube a $V_{IN} - V_{SAT}$, polarizando en inversa el diodo Schottky D1. La corriente fluye desde el Pin 1 hacia el inductor L1 (33 µH), generando una rampa lineal de corriente según la ley de Faraday:\n$$\\frac{di_L}{dt} = \\frac{V_{IN} - V_{SAT} - V_{OUT}}{L}$$\nEsta corriente abastece a la carga mientras almacena energía magnética en el núcleo toroidal del inductor L1.\n\n### 3. Corte del interruptor y recirculación por diodo Schottky\nCuando el comparador PWM finaliza el intervalo de conducción, el interruptor NPN se apaga. Como la corriente por el inductor no puede cambiar instantáneamente, el colapso del campo magnético fuerza el potencial del Pin 2 (OUTPUT) por debajo de tierra. Al caer el Pin 2 a aproximadamente -0.45V, el diodo Schottky D1 entra en conducción directa y canaliza la corriente de recirculación del inductor hacia la carga a través de C2. El uso de un diodo Schottky es estrictamente obligatorio, ya que los diodos de silicio estándar presentan tiempos de recuperación inversa lentos que provocan picos destructivos.\n\n### 4. Filtrado capacitivo de salida y supresión de rizado\nLa corriente de rizado triangular que circula por el inductor L1 se bifurca entre el condensador de salida C2 (220 µF \u002F 25V) y la carga de CC. C2 absorbe la componente alterna y suaviza la tensión de salida, entregando un riel continuo de +5.0V CC con rizado típicamente inferior a 50 mV pico a pico. La magnitud de este rizado depende esencialmente de la Resistencia Serie Equivalente (ESR) de C2:\n$$\\Delta V_{OUT} \\approx \\Delta I_L \\cdot \\text{ESR}$$\n\n### 5. Lazo cerrado de sensado y regulación PWM\nEl Pin 4 (FEEDBACK) monitoriza la tensión de salida tras el inductor L1. En la versión de 5.0V fijos del LM2596, un divisor resistivo de precisión interno adapta la tensión a la referencia bandgap de 1.23V. El amplificador de error amplifica cualquier desviación respecto a la referencia interna y modula el umbral de disparo del comparador PWM frente a la rampa de 150 kHz, ajustando el ciclo de trabajo $D$ para sostener la salida en ±4% en todo el rango operativo.",[26,29,32,35,38,41,44,47,50,53],{"label":27,"value":28},"Tensión de salida regulada","5.0V CC (±4% de tolerancia total: 4.80V a 5.20V)",{"label":30,"value":31},"Rango de voltaje de entrada","7.0V a 40.0V CC (punto nominal de 12.0V)",{"label":33,"value":34},"Corriente de salida continua máxima","3.0A CC (requiere disipador térmico adecuado)",{"label":36,"value":37},"Frecuencia de conmutación del oscilador","150 kHz típico (135 kHz mín., 165 kHz máx.)",{"label":39,"value":40},"Eficiencia de conversión típica","80% para VIN=12V, IOUT=3A, VOUT=5V",{"label":42,"value":43},"Corriente de reposo en reposo (standby)","80 µA típico (pin ON\u002FOFF en nivel alto > 2.0V)",{"label":45,"value":46},"Corriente de reposo operativa","5 mA típico (a VIN=12V, pin de realimentación a tierra)",{"label":48,"value":49},"Umbral de límite de corriente del conmutador","4.5A típico (3.6A mín., 6.9A máx.)",{"label":51,"value":52},"Voltaje de saturación del conmutador interno","1.16V típico a ISW=3.0A (TJ=25°C)",{"label":54,"value":55},"Rizado de voltaje de salida","\u003C 50 mV pico a pico con condensadores de bajo ESR recomendados",[57,58,59,60],"Regulación local eficiente de 5V CC desde buses industriales de 12V o 24V","Etapa de pre-regulación para reguladores lineales LDO para reducir la disipación térmica","Electrónica automotriz y sistemas a batería con amplio rango de entrada de 7V a 40V","Alimentación de placas de microcontroladores y circuitos lógicos de hasta 3A",[62,67,72,76],{"title":63,"trap":64,"solution":65,"severity":66},"El ESR del condensador de salida determina el rizado","Utilizar un condensador electrolítico estándar produce picos de rizado de 200–500 mV, provocando reinicios por caída de voltaje (brownout) o inestabilidad del lazo de control pese a tener alta capacidad.","Especifique condensadores de ESR ultra bajo (Nichicon PL\u002FHE, Panasonic HFQ o polímero sólido) con ESR inferior a 0.1 Ω.
