TIDA-00699

Design files

Overview

This solution was designed to be a broadly applicable automotive off-battery front end power supply for 10-15W systems. There is a focus on EMI/EMC testing and compliance as well to help designers satisfy the regulatory requirements associated with producing an automotive electronic subsystem.

Features
  • Wide-Vin front end power supply for 10-15W systems
  • Off-Battery operation with reverse battery protection
  • Designed and tested for severe cold-crank operation
  • Designed and tested to ISO 7637-2:2004 Pulse 1, 2a, 3a/b and 5b (clamped load dump)
  • Tested for CISPR25 Conducted and Radiated Emissions

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
