It operates from a 2.3V to 5.5V input range, making it suited for single-cell Li-ion or multi-chemistry battery applications where the input voltage can drop below or rise above the regulated output. The 2.5MHz switching frequency allows the use of small external inductors and capacitors, shrinking the total power-stage footprint. The output is adjustable from 2.6V up to 5.14V, covering common 3.3V and 5V rails. The part is housed in a 20-WLP (1.83x2.13 mm) wafer-level package, rated for the industrial temperature range of -40°C to 85°C. ## Non-synchronous topology — external Schottky required The MAX77816CEWP+T does not integrate a synchronous rectifier. An external Schottky diode is required for the boost-side rectification. This adds one BOM component and a small PCB area, but it also avoids the shoot-through risk and gate-drive losses of an integrated synchronous FET at high switching frequencies. For designs that prioritize efficiency at light loads, the external diode's forward drop should be considered in the loss budget. ## Active lifecycle — no obsolescence pressure The MAX77816CEWP+T carries an Active product status from Maxim Integrated, with ROHS3 compliance. This part is suitable for new designs and production builds without near-term supply risk.","metaTitle":"MAX77816CEWP+T Buck-Boost Regulator, 5A, 2.5MHz, 20-WLP","metaDescription":"MAX77816CEWP+T step-up/step-down adjustable regulator, 5A output, 2.5MHz switching, 2.3V-5.5V input, -40°C to 85°C, 20-WLP.
