  • Product introduction

TPS54873 Desactiva la entrada aspirada de 5V, convertidor reductor síncrono de 8A durante el arranque

illustrate

 

Como reguladores CC/CC de SWIFT ™, miembro de la familia de reguladores CC/CC, el convertidor PWM síncrono de baja tensión de entrada TPS54873 integra todos los ingredientes activos necesarios. Incluido en las características enumeradas con sustrato se incluye un amplificador de error de voltaje verdadero y de alto rendimiento capaz de seleccionar componentes de inductor y condensador filtrados de salida para el mayor rendimiento y flexibilidad; un circuito de bloqueo de voltaje secundario para evitar el arranque hasta que el voltaje de entrada alcance los 4 voltios; Un circuito de arranque lento interno o configurado externamente para limitar la corriente de entrada, así como un procesador de buena salida de potencia / restablecimiento lógico útil para señales de falla y secuenciación de energía.

Basado en la confiable aplicación de potencia de salida de precarga, el TPS54873 está diseñado para iniciar solo la fuente de corriente.
