Les kits de conception RTK-251-1PowerBank3 et RTK-251-BuckBoostConverter2 sont certifi\u00e9s USB-IF PD3.0 et sont les premiers d’une nouvelle s\u00e9rie de conceptions de r\u00e9f\u00e9rence pour les applications mettant en \u0153uvre la norme d\u2019alimentation et de communication de donn\u00e9es USB Type-C.<\/p>\n

La carte RTK-251-1PowerBank3 est une conception de r\u00e9f\u00e9rence de bloc d’alimentation de batterie Li-ion \u00e0 3 cellules (connect\u00e9es en s\u00e9rie) qui utilise le contr\u00f4leur R9A02G011<\/a> de type USB PD3.0 et le chargeur de batterie \u00e0 charge directe avec tension limit\u00e9e NVDC (Narrow Voltage Direct Charging) ISL95538B<\/a>. Id\u00e9ale pour les banques d’alimentation USB-C avec plusieurs cellules, la carte de conception de r\u00e9f\u00e9rence comprend un port USB de type C qui prend en charge la fonctionnalit\u00e9 DRP (Dual Role Power), fournissant une alimentation dans les deux sens via les modes d\u2019alimentation de type source et r\u00e9cepteur. Lorsque la batterie de secours est en mode r\u00e9cepteur, elle demande 5V, 9V, 15V ou 20V \u00e0 un fournisseur USB PD3.0 tel qu\u2019un adaptateur secteur. Lorsque la batterie de secours est en mode source, la batterie Li-ion fournit une tension allant de 5V \u00e0 20V \u00e0 un ordinateur (PC), une tablette ou un smartphone. De plus, le RTK-251-1PowerBank3 modifie son r\u00f4le de DRP en fonction de la capacit\u00e9 restante de la batterie affich\u00e9e sur les voyants de la carte.
\nLe RTK-251-BuckBoostConverter2 est un module DC \/ DC qui utilise le contr\u00f4leur USB PD3.0 R9A02G011 et le r\u00e9gulateur de tension buck-boost bidirectionnel ISL95338<\/a>. La carte de conception de r\u00e9f\u00e9rence RTK-251-BuckBoostConverter2 est id\u00e9ale pour les concentrateurs USB-C dans le cadre de la connexion de l’adaptateur secteur USB-PD. Il accepte 19V avec une alimentation d’entr\u00e9e de 4,73 A DC et produit une alimentation de sortie VBUS compatible USB-PD3.0. La carte de conception de r\u00e9f\u00e9rence prend en charge l’alimentation programmable (PPS) et dispose de deux prises USB de type C pour la sortie d’alimentation VBUS. <\/p>\n

\u00ab Les conceptions de r\u00e9f\u00e9rence RTK-251-1PowerBank3 et RTK-251-BuckBoostConverter2 acc\u00e9l\u00e8rent consid\u00e9rablement les temps de d\u00e9veloppement des clients en fournissant des solutions test\u00e9es et compl\u00e8tes pr\u00eates \u00e0 int\u00e9grer n’importe quelle conception \u00bb, a d\u00e9clar\u00e9 Andrew Cowell, vice-pr\u00e9sident de la division des Syst\u00e8mes Optiques et Batteries, Renesas Electronics Corporation. \u00ab Les produits Renesas USB-PD et USB-C, leaders du march\u00e9, permettent des facteurs de forme plus petits, une charge plus rapide et une efficacit\u00e9 sup\u00e9rieure pour une dur\u00e9e de vie de la batterie remarquablement plus longue. \u00bb<\/p>\n
