Le LTM8005 fonctionne sur une plage de tension d\u2019entr\u00e9e de 5V \u00e0 38V et peut g\u00e9n\u00e9rer un courant r\u00e9gul\u00e9 de 1,6A pour une tension de sortie pouvant atteindre 38V. Une inductance externe, permet de configurer facilement le LTM8005 dans les diff\u00e9rents modes de fonctionnement avec les architectures en modes\u00e9l\u00e9vateur, abaisseur-\u00e9l\u00e9vateur, abaisseur et SEPIC avec une inductance coupl\u00e9e. <\/p>\n

La version de classe H, de grande fiabilit\u00e9, assure un fonctionnement de -40\u00b0C \u00e0 150\u00b0C. La large plage de tension d\u2019entr\u00e9e et le fonctionnement \u00e0 150\u00b0C rendent ce \u00b5Module contr\u00f4leur de LED appropri\u00e9 aux applications d\u2019\u00e9clairage de l\u2019automobile et de l\u2019industrie.<\/p>\n

La fr\u00e9quence de fonctionnement peut \u00eatre r\u00e9gl\u00e9e de 100kHz \u00e0 1MHz, et la modulation de fr\u00e9quence avec \u00e9talement de spectre, int\u00e9gr\u00e9e, contribue \u00e0 am\u00e9liorer la compatibilit\u00e9 \u00e9lectromagn\u00e9tique. Le contr\u00f4le de la luminosit\u00e9 des LED peut \u00eatre effectu\u00e9 via la broche analogique CTRL et un gradateur PWM jusqu\u2019\u00e0 un rapport de 1 : 3 000. Le LTM8005 procure des dispositifs de s\u00e9curit\u00e9 comme une protection avec d\u00e9connexion de la sortie en cas de court-circuit, une protection en cas de LED ouverte, une limite programmable du courant d\u2019entr\u00e9e, de m\u00eame que le suivi des courants d\u2019entr\u00e9e et de sortie.<\/p>\n
