Le MAX20069 constitue la premi\u00e8re solution de l\u2019industrie int\u00e9grant 4 drivers de r\u00e9tro-\u00e9clairage LED 150 mA \u00e0 commande I2C et un circuit de polarisation TFT-LCD (Thin Film Transistor Liquid Crystal Display) \u00e0 4 sorties, dans un seul circuit int\u00e9gr\u00e9. Le MAX20069 r\u00e9duit l’empreinte sur carte jusqu’\u00e0 un tiers par rapport aux composants concurrents les plus proches. <\/p>\n

Les \u00e9crans automobiles sont de plus en plus grands et sophistiqu\u00e9s alors que les constructeurs souhaitent attirer les acheteurs gr\u00e2ce \u00e0 davantage de fonctions d\u2019information et de divertissement. Des \u00e9tudes sugg\u00e8rent un taux de croissance annuel compos\u00e9 de 39% pour le march\u00e9 des \u00e9crans 8 pouces utilis\u00e9s dans les \u00ab\u00a0clusters\u00a0\u00bb (regroupements) d’instruments, la console centrale et les syst\u00e8mes d’affichage t\u00eate haute \u00e0 bord des v\u00e9hicules. Les clusters d’instruments devraient bient\u00f4t migrer vers des \u00e9crans de 12,3 pouces. Par cons\u00e9quent, les concepteurs de syst\u00e8mes d’info-divertissement automobile auront besoin de solutions de puissance offrant pr\u00e9cision, souplesse et encombrement r\u00e9duit, pour r\u00e9pondre \u00e0 des exigences syst\u00e8me de plus en plus complexes.<\/p>\n

Le MAX20069 prend en charge des \u00e9crans de taille et r\u00e9solution sup\u00e9rieure en fournissant une tension d’alimentation analogique positive (PAVVD) et une tension d’alimentation analogique n\u00e9gative (NAVDD), toutes deux n\u00e9cessaires aux panneaux LTPS (Low Temperature Poly Silicon, ou poly-silicium basse temp\u00e9rature), qui offrent une r\u00e9solution plus \u00e9lev\u00e9e et un co\u00fbt inf\u00e9rieur \u00e0 ceux des panneaux en silicium amorphe actuellement utilis\u00e9s. Le CI prend aussi en charge les courants plus \u00e9lev\u00e9s dont les \u00e9crans nouvelle g\u00e9n\u00e9ration ont besoin, avec 150 mA par canal dans le cas de ce pilote de LED \u00e0 quatre canaux pour \u00e9crans 8 pouces ou plus, \u00e0 r\u00e9solution \u00e9lev\u00e9e. Le MAX20069 fonctionne dans la plage de temp\u00e9rature allant de -40\u00b0C \u00e0 +105\u00b0C et se pr\u00e9sente en bo\u00eetier TQFN de 6 x 6 mm. <\/p>\n
