U3V16x Step-Up Voltage Regulators
 |
The U3V16Fx family of compact boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 1.3 V. (Note: The minimum start-up voltage is 2.7 V; see the product web page for details.) They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 85% to 95%.
The regulators actively limit the instantaneous input currents to 2 A when boosting, and input currents up to around 1.6 A can typically be maintained for many minutes without triggering thermal shutdown, though the actual performance depends on the input and output voltages as well as external factors such as ambient temperature and airflow. For boost regulators, the output current equals the input current times the efficiency divided by the boost ratio of VOUT to VIN, so the more you are boosting, the lower the maximum output current will be (see the maximum continuous output current section below for performance graphs).
Warning: This boost regulator uses the typical topology that connects the input to the output through an inductor and diode, with nothing to completely break that current path. Therefore, the input voltage will go through to the output even when the regulator is disabled, and exposure to short circuits or other excessive loads will damage the regulator. This regulator also does not have protection against reverse voltage.
