Automotive discrete SBC pre-boost, post-buck reference design using CAN

The TIDA-01429 reference design uses a wide input voltage boost controller followed by a wide input voltage buck converter set to 5.0V. A 5.0V supply is used to power the controller area network (CAN) transceiver, and a compact 3.3V fixed-voltage linear dropout (LDO) regulator is used to power the C2000 microcontroller. This design has been tested for CISPR 25 radiated emissions according to the anechoic chamber (ALSE) method, CISPR 25 conducted emissions using the voltage method, and Bulk Current Injection (BCI) resistance according to ISO 11452-4, all tested at CAN communication operates at a speed of 500KBPS. This is an Electromagnetic Compatibility (EMC) tested, 3-level power tree reference design using Controller Area Network (CAN) that can be used in a variety of automotive applications that require operation at input voltages as low as 3.5V. A system basis chip (SBC) is an integrated circuit (IC) that combines several typical building blocks of a system, including transceivers, linear regulators, and switching regulators. While these integrated devices can provide size and cost savings in many applications, integrated devices do not work well in every situation. For applications that are less suitable for using an SBC, a better approach is to build discrete implementations of the above building blocks to create a discrete SBC.

Reinforced Isolated Phase Current Sensing Reference Design with Small Delta-Sigma Modulator

This reference design implements a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors.
