Abstract

The Texas Instruments LM63635DNEVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM63635Cx family of buck regulators. The LM63635Cx is a family of easy-to-use synchronous step-down DC/DC converters capable of driving up to 3.25 A of load current from an input voltage of 3.5 V to 36 V. See the LM63635 and LM63635C data sheets for additional features, detailed description, and available options. Table 1-1 provides a list of regulator device numbers that can be used with the LM63635DNEVM. Note that the EVM must be modified for use with some of these device numbers. See Section 2 for more details.
