Analog Devices Inc. ADP5056 Triple Buck Regulator Power Solution
Analog Devices Inc. ADP5056 Triple Buck Regulator Integrated Power Solution 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 ADP5056 Solution allows a direct connection to high input voltages up to 18V with no regulators.
All channels on the ADI ADP5056 Solution integrate high-side and low-side power metal-oxide-semiconductor field-effect transistors (MOSFETs) to achieve an optimized efficiency solution. Channel 1 and Channel 2 deliver a programmable output current of 3.5A or 7A or provide a single output with up to 14A of current in parallel operation. Channel 3 offers a programmable output current of 1.5A or 3A.
The ADP5056 Power Solution offers a switching frequency that can be programmed or synchronized to an external clock. The ADP5056 contains an enable pin (ENx) on each channel for easy power-up sequencing or adjustable under-voltage lockout (UVLO) threshold.
The ADP5056 is rated at -40°C to +150°C junction temperature and is housed in a 43-terminal land grid array (LGA) package.
