Les contrôleurs PWM analogiques compacts, avec des drivers MOSFET synchrones intégrés, assurent un comportement en mode transitoire remarquable. Ils fonctionnent sur la vaste plage de tension de 4,5 à 30 VCC à une fréquence de commutation de 300 kHz. Ils disposent également d’un réglage du temps mort ajustable en usine qui permet aux concepteurs d’optimiser la performance grâce au large choix de transistors MOSFET utilisables. Associés aux MOSFET MCP87xxx, ils produisent des solutions de conversion de puissance continu\/continu de haut rendement pouvant dépasser 96%. Cette famille de MOSFET rapides dispose d’un FOM très faible et tient dans des boîtiers PDFN au standard de l’industrie. Les modèles MCP87022, MCP87050, et MCP87055 offrent une résistance électrique à l’état passant de respectivement 2,2 mohms, 5,0 mohms, et 5,5 mohms, et facilitent la conception de systèmes de conversion de puissance de haut rendement. Ils complètent aussi le portefeuille propriétaire existant de microcontrôleurs PIC SMPS dédiés aux alimentations à découpage et de contrôleurs numériques de signaux dsPIC33 “GS”.  <\/p>\n

Les contrôleurs PWM sont proposés en boîtier DFN 10 broches de 3 x 3 mm alors que les MOSFET sont encapsulés en boîtiers PDFN  8 broches de 5 x 6 mm pour les MCP87022 et MCP87050 et de 3.3 x 3.3 mm pour le MCP87055. Une carte d’évaluation est également disponible avec un outil de calcul de pertes basé sur Excel et un guide utilisateur.<\/p>\n
