Overview

The DC3004A is a demonstration circuit for the LT8253, a 40V 4-switch buck-boost controller optimized for automotive USB Type-C Power Delivery (PD) applications. It supports up to 60W output power with a voltage range of 3.3V to 21V at up to 3A. The design integrates a Cypress CCG3PA (CYPD3196) USB-C port controller to manage power contract negotiations for USB PD 3.0, PPS, and legacy profiles including QC 4.0 and Apple 2.4A. Operating at a 400kHz switching frequency, the circuit utilizes Spread Spectrum Frequency Modulation (SSFM) to meet CISPR 25 Class 5 EMI standards and achieves typical efficiency of 94.3% at 12V input.

Use Cases

  • Automotive USB-C charging ports
  • 60W Power Delivery systems
  • Multi-protocol fast charging applications
  • High-efficiency buck-boost power conversion
