Title (EN) INPUT UNDER-VOLTAGE PROTECTION CIRCUIT
(FR) CIRCUIT DE PROTECTION CONTRE LA SOUS-TENSION D'ENTRÉE
(ZH) 一种输入欠压保护电路
Abstract:
(EN) Provided is an input voltage protection circuit (100) capable of realizing functions such as input under-voltage protection and feedforward compensation without requiring additional leads and sampling resistors. The above two functions use the same lead at different times and are independent from each other. The invention has high precision, and can further reduce production costs and expand ranges of applications of a controller and a switching power supply.
(FR) L'invention concerne un circuit de protection contre la tension d'entrée (100) apte à assurer des fonctions telles qu'une protection contre la sous-tension d'entrée et une compensation de correction aval sans nécessiter de résistances d'échantillonnage et de conducteurs supplémentaires. Les deux fonctions susmentionnées font appel au même conducteur à des moments différents et sont indépendantes l'une de l'autre. L'invention dispose d'une précision élevée, et peut en outre réduire les coûts de production et étendre les plages d'applications d'un dispositif de commande et d'une alimentation électrique de commutation.
(ZH) 一种输入电压保护电路(100),不需要增加额外的引脚和采样电阻,就能实现输入欠压保护和前馈补偿等功能,两种功能分时复用引脚,而且功能相互独立,精度高,能够进一步降低生产成本,拓宽控制器以及开关电源的应用范围。
