Switching frequency100-2200 kHz
Output 15 V / 1.5 A
IC revisionE1

Description

The TIDA-01429 reference design implements a wideinput voltage boost controller, followed by a wide input voltage buck converter set to 5.0 V. The 5.0 V supply is used for powering a Controller Area Network (CAN) transceiver and a compact fixed 3.3 V linear drop-out (LDO) regulator for supplying the C2000 microcontroller. This design has been tested for CISPR 25 radiated emissions per absorber lined shielded enclosure (ALSE) method, CISPR25 conducted emissions via the voltage method, and for immunity to Bulk Current Injection (BCI) per ISO 11452-4, all with CAN communication operating at 500 KBPS. This is a electromagnetic compliance (EMC) vetted 3-stage power tree with controller area network (CAN) reference design that can be used in many automotive applications requiring operation with input voltages as low as 3.5 V.
