Texas Instruments LM53601-Q1 | Demoboard TIDA-01428

Description

The TIDA-01428 reference design implements a 1-A, wide-VIN, buck converter to 3.3 V followed by a compact, low-input voltage, fixed 5-V boost converter for powering a controller area network (CAN) physical layer interface. The design has been tested for CISPR 25 radiated emissions and conducted emissions using the voltage method and for immunity to bulk current injection (BCI) per ISO 11452-4 with CAN communication operating at 500 KBPS. The TIDA-01428 is an EMC-vetted power tree plus CAN reference design that can be used in many automotive applications. A system basis chip (SBC) is an integrated circuit (IC) that combines many typical building blocks of a system, which includes transceivers, linear regulators, and switching regulators. While these integrated devices can offer size and cost savings in a number of applications, the integrated devices do not work in every case. For applications where an SBC is not a good fit, it might be beneficial to build a discrete implementation of these aforementioned building blocks thus making a discrete SBC.
