Ever since the release of our original adjustable boost regulators, customers have been requesting higher-power versions. Doing power systems right is not easy, and minute differences in component choices and layout can make a huge difference in performance: we went through three different failed designs before arriving at our new U3V50x family of step-up voltage regulators, which we think offers a great balance of size, performance, and price.
These new boost regulators can generate up to 30 V from input voltages as low as 2.9 V while allowing for input currents as high as 5 A and offering typical efficiencies of 80% to 95%, making these our most powerful boost regulators. The regulators include built-in reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout that keeps the modules from behaving erratically when the input voltage gets too low. The U3V50x family includes versions with fixed 5 V, 6 V, 9 V, 12 V, or 24 V outputs and versions with adjustable 4 V to 12 V or 9 V to 30 V outputs.
The compact boards (0.6″ × 1.9″) have two mounting holes and can be assembled with the included 5mm-pitch terminal blocks or 0.1″ header pins.
