1.1 Background

The TPS54372EVM-215 evaluation module uses the TPS54372

tracking/termination synchronous buck regulator to provide an output voltage

TTQ

that is one half the voltage V

DDQ

from a nominal 3.3-V or 5-V input. Rated

input voltage and output current range is given in Table 1–1. These evaluation

modules are designed to demonstrate the small PCB areas that may be

achieved when designing with the TPS54372 regulator. The switching

frequency is set at a nominal 700 kHz, allowing the use of a small footprint

1.0-µH output inductor. The MOSFETs of the TPS54372 are incorporated

inside the TPS54372 package. This eliminates the need for external

MOSFETs and their associated drivers. The low drain-to-source on resistance

of the MOSFETs gives the TPS54372 high efficiency and helps to keep the

junction temperature low at high output currents. The compensation

components external to the IC allow flexibility in choosing output filter

components voltage and a customizable loop response.
