ADP5040 Overview
The ADP5040 bines one high performance buck regulator and two low dropout regulators (LDO) in a small 20-lead LFCSP to meet demanding performance and board space requirements. The high switching frequency of the buck regulator enables the use of tiny multilayer external ponents and minimizes board space. When the MODE pin is set to logic high, the buck regulator operates in forced pulse width modulation (PWM) mode.
