Hardware

The SLVP089 Synchronous Buck Converter Evaluation Module (SLVP089) provides a method for evaluating the performance of the TL5001 pulse-width- modulation (PWM) controller. The device contains all of the circuitry necessary to control a switch-mode power supply in a voltage-mode configuration. This manual explains how to construct basic power conversion circuits including the design of the control chip functions and the basic loop. This chapter in- cludes the following topics:
