Powerful new U3V50x boost regulators

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.

For other regulator options, you can take a look at our full selection of step-up voltage regulators, step-down voltage regulators, and step-up/step-down regulators.

What does the "Enable" pin do? Do I need to pull that high, or...?
Hi, Phil.

We detail the connections for those regulators (including the ENABLE pin) on their respective product pages. The ENABLE pin can be driven low (under 0.7 V) to put the board into a low-power state. If you do not need this feature, you should leave the ENABLE pin disconnected.

Does the output(VOUT) have a decoupling capacitor? If yes, of what value?
Hello.

The output capacitance varies across the different versions of this regulator, but it is on the order of a few hundred microfarads. Can you tell me why you are interested in this?
