The ADP5135 combines three high performance buck regulators. It is available in a 24-lead 4 mm ? 4 mm LFCSP.The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set to high, the buck regulators operate in forced PWM mode.
