TLE9278BQXV33XUMA1 Description

Infineon’s TLE9278BQXV33XUMA1 offers the highest level of integration at the smallest footprint for automotive applications requiring multiple channels of CAN transceivers like gateways and high-end Body Control Modules (BCM). A high-efficient Switch Mode Power Supply (SMPS) buck regulator provides an external 3.3 V output voltage of up to 750 mA. At the same time, an additional DC/DC boost converter supports applications or conditions at low supply input voltages.
