DCDC Convertor & Multi Output Regulator TB9045FNG is a multi output power supply IC for automotive system power supply incorporating 2 DCDC convertors, a series power supply and 3 tracking regulators. Both high efficiency and low noise output are concurrently achieved by a DCDC power supply and a series power supply, respectively. It incorporates various monitoring functions for abnormalities in power supply and MCU, and enables transmitting monitoring statuses HTSSOP48-P-300-0.50 to an external system via SPI communication. Weight: 204.6mg (typ.)
