1.1 Description

The TPS544C26EVM is an evaluation module for the TPS544C26 DC/DC synchronous buck converter with a digital I2C and a serial voltage identification (SVID) interface to accommodate Intel processors. The evaluation module accepts an 8-V to 16-V input and can deliver an output current up to 35 A. The converter uses D-CAP+™ control scheme for fast transient response, using less output capacitance to save board space. Rated input voltage and output current range for the evaluation module are given in Table 1-1. Figure 1-1 highlights the user interface items associated with the EVM.
