LM63615DQPWPRQ1 Description

The LM63615DQPWPRQ1 regulator is an easy-to-use, synchronous, step-down DC/DC converter designed for rugged automotive applications. The LM63615DQPWPRQ1 can drive a load current of up to 1.5 A or 2.5 A from an input voltage of up to 36 V. In a tiny solution size, the converter offers great light-load efficiency and output precision. Features like a RESET flag and precision provide flexible and user-friendly solutions for a wide range of applications. Automatic frequency foldback enhances efficiency while maintaining tight load regulation at low loads.
