Buck-boost regulator for battery-powered rail generation
The MAX77813EWP+T is a buck-boost switching regulator from Analog Devices that handles both step-down and step-up/step-down conversion. That means it can regulate an output voltage whether the input is higher, lower, or equal to the output — a common requirement in battery-powered equipment where the cell voltage decays below the regulated rail over discharge. The part uses buck and boost topologies internally to cover that range without a separate boost stage.
Active lifecycle and ROHS3 compliance — no near-term LTB risk
It is also ROHS3 compliant, meeting the latest EU hazardous-substance restrictions for lead, mercury, cadmium, and the four phthalates. For a BOM line that needs a multi-chemistry battery regulator, this part is a safe choice for new designs and ongoing production.
Packaging and procurement — Tape & Reel or Cut Tape
The MAX77813EWP+T is offered in Tape & Reel (TR) and Cut Tape (CT) packaging options. Tape & Reel suits automated pick-and-place assembly lines; Cut Tape is convenient for prototyping and low-volume builds.
