The TPS562212 is a single, advanced emulated current mode (AECM) control, synchronous buck converter that is able to deliver 2-A continuous output current and provides 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 pin, 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 TPS562212EVM is a single, synchronous buck converter providing 3.3 V at 2 A from 4.2-V to 18-V input. This user’s guide describes the TPS562212EVM performance.

A summary of the TPS562212EVM 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.
