Available from Mouser Electronics, Maxim Integrated MAX20461 Automotive High-Current Step-Down Converters combine a 3A high-efficiency, automotive-grade, step-down converter, a USB Type-C/BC1.2 host charger emulator, and high bandwidth USB protection switches for automotive USB 2.0 host applications. Additionally, the MAX20461 includes a USB load current-sense amplifier and a configurable feedback adjustment circuit that provides automatic USB voltage compensation for voltage drops in captive cables often found in automotive applications. The Converters limit the USB load current using both a fixed internal peak-current threshold and a user-configurable external current-sense USB load threshold. The Maxim MAX20461 Converters are optimized for high-frequency operation and include programmable frequency selection from 310kHz to 2.2MHz, allowing optimization of efficiency, noise, and board space based on the application requirements.
