Maxim Integrated MAX20028ATJA/VY+, Triple-Channel, Step Down DC-DC Converter, 3A 32-Pin, TQFN

740

The Maxim Integrated MAX20028 power-management integrated circuit (PMIC) is a 2.1MHz, multichannel, DC-DC converter designed for automotive applications. The device integrates three supplies in a small footprint. The device includes one high-voltage step down controller (OUT1) designed to run directly from a car battery, and two low voltage step-down converters (OUT2/OUT3), cascaded from OUT1. Under no-load conditions, the MAX20028 consumes only 30μA of quiescent current, making it ideal for automotive applications.
