描述 |
产品概述 The TMI3455 is a synchronous buck controller mainly for widely varying input step-down regulator applications. The control method is based upon current mode control that enables maximum performance under transient conditions. The output voltage can be either programmed by the FB pin or configured by the I2C interface from 3.0V to 28V with 20mV per step. It also features an adjustable soft-start function and offers protection features including input UVLO, cycle-by-cycle current limit, output average current limit or OVP and thermal shutdown. In addition, it features selectable Forced Continuous Conduction Mode (FCCM) or Discontinuous Conduction Mode (DCM) operation for light load. |
