1.1 Background
The TPS54010 dc/dc converter is designed to provide up to a 14-A output from
an input voltage source of 2.2 V to 4 V. Rated input voltage and output current
range are given in Table 1−1. This evaluation module is designed to
demonstrate the small PCB areas that may be achieved when designing with
the TPS54010 regulator and does not reflect the high efficiencies that may be
achieved when designing with this part. The switching frequency is set at a
nominal 700 kHz, allowing the use of a small footprint 0.68-µH output inductor.
The high- and low-side MOSFETs are incorporated inside the TPS54010
package along with the gate drive circuitry. The low drain-to-source on
resistance of the MOSFETs allows the TPS54010 to achieve high efficiencies
and helps to keep the junction temperature low at high output currents. The
compensation components are provided external to the IC and allow for an
adjustable output voltage and a customizable loop response. The TPS54010
is a full-featured device including programmable undervoltage lockout,
synchronization, adjustable switching frequency, enable, and power-good
functions.

Note: Maximum PVIN for the TPS54010 is 4 V. To operate the TPS54010EVM-067 at PVIN
greater than 3.5 V may require that the compensation network be adjusted.
