DCDC Convertor & Multi Output Regulator

TB9044AFNG is a multi output power supply IC for automotive

system power supply incorporating a DCDC convertor, 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

to an external system via SPI communication.
