Description

This compact (15.2mm x 15.2mm) switching step-up (or boost) voltage regulator efficiently generates 5 V from input voltages as low as 1.3 V and handles continuous input currents up to around 4 A. (Note: minimum start-up voltage is 2.7 V, but it operates down to 1.3 V after that.) The pins have a 2.54mm spacing, making this board compatible with standard solderless breadboards and perfboards.

The U3V40Fx family of boost (step-up) voltage regulators are high-efficiency synchronous switching regulators that generate higher output voltages from input voltages as low as 1.3 V. (Note: minimum start-up voltage is 2.7 V; see the connections section for details.) The regulators actively limit the instantaneous input currents to 9.5 A, and the input current can typically be as high as 4.5 A for several seconds before the thermal protection activates. Input currents of around 3.5 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).

These regulators feature a variety of built-in protections, including cycle-by-cycle input current limiting, soft-start, programmable under-voltage lockout, output over-voltage protection, and over-temperature shutdown.

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.

The U3V40x family includes five versions with fixed output voltages ranging from 5 V to 12 V.
