GENERAL DESCRIPTION

The ADP5052 combines four high performance buck regulators

and one 200 mA low dropout (LDO) regulator in a 48-lead LFCSP

package that meets demanding performance and board space

requirements. The device enables direct connection to high input

voltages up to 15 V with no preregulators.

Channel 3 and Channel 4 integrate both high-side and low-side

MOSFETs to deliver output current of 1.2 A.

The switching frequency of the ADP5052 can be programmed

or synchronized to an external clock. The ADP5052 contains a

precision enable pin on each channel for easy power-up sequencing

or adjustable UVLO threshold.

Channel 1 and Channel 2 integrate high-side power MOSFETs and

low-side MOSFET drivers. External NFETs can be used in low-side

power devices to achieve an efficiency optimized solution and

deliver a programmable output current of 1.2 A, 2.5 A, or 4 A.

Combining Channel 1 and Channel 2 in a parallel configuration

can provide a single output with up to 8 A of current.

The ADP5052 integrates a general-purpose LDO regulator with

low quiescent current and low dropout voltage that provides up

to 200 mA of output current.
