Product Details
The ADP5055 combines three high performance buck regulators in a 43-terminal land grid array (LGA) package to meet 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 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.
The ADP5055 is rated at −40°C to +150°C junction temperature.
