The converter operates at a regulated 5.5MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load currents, the TPS8267x converter operates in power-save mode with pulse frequency modulation (PFM).

With this method, the solder mask opening is made larger than the desired land area, and the opening size is defined by the copper pad width.
