Beschreibung

The LTC®3376 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1.5A power stages, powered from independent 3V to 20V inputs. The DC/DCs are assigned to one of fifteen power configurations via pin strappable CFG0 to CFG3 pins. The LTC3376 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.
