This application note presents several reference designs that implement the LM274X synchronous buckcontroller. The designs address various applications in a wide variety of configurations. The designreference will give an engineer a head start on their project, with designs encompassing sequencing,tracking, synchronizing multiple power supplies, DDR termination, buck-boost, low PCB real esta - Current Limit Foldback Improves Short Circuit Protection in LM274X Family (Rev. B)PDF, 89 Kb, Revisión: B, Archivo publicado: abr 23, 2013
This application report discusses the function of the low side current limit used in the LM274X, andpresents a simple method to enhance the short-circuit protection. the current limit is required to protect thepower components from thermal stress, which can reduce life span. Typically, high side current limitdesigns require an internal rising edge blanking time or external filter to avoid no - Optmiz Pwr Cntrlr Dsigns thru Utiliz Freq & Sync, Ext Ref, Trking & Precis ENPDF, 359 Kb, Archivo publicado: abr 24, 2008
