illustrate
El convertidor reductor de rectificación síncrona del LM3103 tiene todas las características necesarias para lograr una alta eficiencia y rentabilidad como regulador reductor. Se suministra con un voltaje de salida tan bajo como 0.6V a 0.75A a la carga. Dual N-channel synchronous MOSFET switches allow low component count, reducing complexity and board size.
A diferencia de la mayoría de los otros reguladores COT, el LM3103 no depende de condensadores de estabilidad de salida ESR y está diseñado para sobresalir con condensadores de salida cerámicos y otros condensadores de salida ESR muy bajos. It eliminates the need for loop compensation, fast load transient response and simple circuit implementation. The operating frequency remains almost inversely different from the line due to the inverse relationship between input voltage and on-time. The operating frequency can be externally programmed up to 1 MHz. Protection features include V-undervoltageCCLockout, output overvoltage protection, thermal shutdown, gate drive undervoltage lockout. El LM3103 está disponible en un paquete eTSSOP-16 térmicamente mejorado.
