LTC3376IY#PBF

LTC3376 is a highly flexible multi output power supply IC. This device includes four synchronous buck converters. The DC/DCs are assigned to one of fifteen power configurations via pin strappable CFG0 to CFG3 pins. It includes the integration of ceramic capacitors into the package for the BST pins thereby saving PCB space. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock. The operating mode for all DC/DCs may be programmed via the SYNC/MODE pin for Burst Mode or forced continuous mode operation. The PGOOD1 to PGOOD4 outputs indicate when each enabled DC/DC is within a specified percentage of its final output. Current monitors allow for external monitoring of each buck’s load. The EXTVCC pin allows for the internal circuitry to run from a 3V to 5.5V rail for improved efficiency. It is used in application such as telecom/industrial, 12V distributed power systems etc.
