The TPS563212 is a single, advanced emulated current mode (AECM) control, synchronous buck converter, that is able to deliver 3-A continuous output current, providing selectable Eco-mode operation or FCCM operation and a selectable power-good indicator or external soft start by the configuring the MODE pin. Power sequencing is possible by correctly configuring the enable, power-good indicator, or external soft start. The device implements an AECM control, which can get fast transient response with fixed frequency. The fast transient response results in low voltage drop and fixed frequency brings a better jitter permanence and predictable frequency for EMI design. The optimized internal compensation network minimizes the external component counts and simplifies the control loop design over a wide voltage output range. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.

The TPS563212EVM is a single, synchronous buck converter providing 3.3 V at 3 A from a 4.2-V to 18-V input. This user’s guide describes the TPS563212EVM performance.

A summary of the TPS563212EVM performance specifications is provided in Table 2-1. Test specifications are given for an input voltage of V_IN = 12 V and an output voltage of 3.3 V, unless otherwise noted. The ambient temperature is 25°C for all measurement, unless otherwise noted.

This evaluation module is designed to provide access to the features of the TPS563212. Some modifications can be made to this module.

The TPS563212 has a MODE pin that can offer two different states of operation under light load conditions, and offer two options for the function of Pin 1.
