General Description

The ADP5041 combines one high performance buck regulator and two low dropout (LDO) regulators in a small 20-lead LFCSP to meet demanding performance and board space requirements.

The high switching frequency of the buck regulator enables use of tiny multilayer external components and minimizes board space.

When the MODE pin is set to logic high, the buck regulator operates in forced PWM mode.
