Avec le circuit élévateur de tension et la circuiterie de compensation intégrés, ce régulateur ne requiert que peu de composants externes. La fréquence de découpage fixée à 704 KHz et le courant de sortie maximal contrôlé par l’utilisateur minimise la taille des composants de filtrage. Une interface compatible I2C fournit les capacités de contrôle requises par les systèmes complexes ainsi que les informations de diagnostique pour les rapports d’erreurs système. Une broche Sleep est aussi présente pour minimiser la consommation et pour éteindre rapidement le composant sans avoir à utiliser l’I2C. Des caractéristiques de contrôle pour le courant de sortie Sink et Source sont aussi intégrées.
\nCe circuit est proposé en boîtier QFN-16 très compact de seulement 3 x3 mm avec une semelle pour la dissipation thermique (suffixe ES). Il est garanti sans plomb avec un étamage 100% étain mat.<\/p>\n
