We are excited to introduce our new compact and efficient U3V16Fx family of boost voltage regulators, which can generate higher voltages from input voltages as low as 1.3 V (the minimum startup voltage is 2.7 V, but they will operate down to 1.3 V after that). It’s awesome how much power these deliver in such a tiny package! It’s a little difficult to quickly convey the power or current capabilities of boost converters, since the output power is limited by the input current (which can be up to 2 A with this new family), but we usually care about the output current, which is inversely proportional to the ratio by which you are boosting the voltage. For instance, if you are tripling your voltage from 3 V to 9 V, the maximum possible output current would be one third of that 2 A maximum input (assuming 100% efficiency). Continuous currents will be a little lower than peaks, and once you factor in real world efficiency (typically 80-95%), you can expect these kinds of maximum currents:
Efficiency is also a bit hard to capture without a ton of graphs, but here’s an example from the 12 V version:
Typical efficiency of 12V Step-Up Voltage Regulator U3V16F12.
The U3V16x family includes seven versions with fixed output voltages ranging from 3.3 V to 15 V:
- U3V16F3: Fixed 3.3V output
- U3V16F5: Fixed 5V output
- U3V16F6: Fixed 6V output
- U3V16F7: Fixed 7.5V output
- U3V16F9: Fixed 9V output
- U3V16F12: Fixed 12V output
- U3V16F15: Fixed 15V output
These new regulators are the same size as the popular U3V12Fx boost regulators, which we had to discontinue due to key components becoming obsolete, and they offer superior performance, so they should work as drop-in replacements for those older regulators in most applications.
