6. Application Information

The LM53600-Q1 and LM536013QDSXTQ1 are step-down DC-DC converters typically used to convert higher DC voltages to lower DC voltages with a maximum output current of 1A or 650mA. The following design procedure can be used to select components for the LM53600-Q1 or LM53601-Q1. Alternatively, a complete design can be generated using the WEBENCH® design tool. The tool utilizes an iterative design process and provides access to a comprehensive component database. This allows the tool to create optimized designs and allows users to experiment with various design options.
