Medical applications

The switching frequency of the ADP5055 can be programmed

or synchronized to an external clock. The ADP5055 contains an

enable pin (ENx) on each channel for simple power-up

sequencing or adjustable undervoltage lockout (UVLO) threshold.

The ADP5055 integrates a high precision 8-bit digital-to-analog

converter (DAC) to enable the output voltage dynamic voltage

scaling (DVS) via the PMBus®-compatible, 2-wire interface. The

PMBus interface provides other flexible configurations, such as

start-up and shutdown sequence control, individual forced pulse-

width modulation or power saving mode (FPWM or PSM)

selection, an output discharge switch, and a power-good signal.

GENERAL DESCRIPTION

The ADP5055 combines three high performance buck regulators

in a 43-terminal land grid array (LGA) package that meets the

demanding performance and board space requirements. The

device enables direct connection to high input voltages up to

18 V with no preregulators.

All channels integrate both high-side and low-side power metal-

oxide semiconductor field effect transistors (MOSFETs) to achieve

an efficiency optimized solution. Channel 1 and Channel 2 deliver

a programmable output current of 3.5 A or 7 A or provide a single

output with up to 14 A of current in parallel operation. Channel 3

delivers a programmable output current of 1.5 A or 3 A.

The ADP5055 is rated at −40°C to +150°C junction temperature.

Note that throughout this data sheet, multifunction pins, such

as SYNC/MODE, are referred to either by the entire pin name

or by a single function of the pin, for example, SYNC, when

only that function is relevant.
