Description

The ADP5056 combines three high performance buck regulatorsin a 43-terminal land grid array (LGA) package that meets thedemanding performance and board space requirements. Thedevice enables direct connection to high input voltages up to18 V with no preregulators.All channels integrate both high-side and low-side power metaloxide semiconductor field effect transistors (MOSFETs) to achievean efficiency optimized solution. Channel 1 and Channel 2deliver a programmable output current of 3.5 A or 7 A, orprovide a single output with up to 14 A of current in paralleloperation. Channel 3 delivers a programmable output currentof 1.5 A or 3 A.The switching frequency of the ADP5056 can be programmedor synchronized to an external clock. The ADP5056 contains anenable pin (ENx) on each channel for easy power-up sequencingor adjustable undervoltage lockout (UVLO) threshold.The ADP5056 integrates start-up/shutdown sequence control,forced pulse-width modulation/power saving mode (FPWM/PSM)selection, an output discharge switch, and a power-good signal.The ADP5056 is rated at ?40?C to +150?C junction temperature.Note that throughout this data sheet, multifunction pins, suchas SYNC/MODE, are referred to either by the entire pin nameor by a single function of the pin, for example, SYNC, whenonly that function is relevant.
