5V Step-Up/Step-Down Voltage Regulator S13V30F5

This powerful synchronous switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.8 V and 22 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The board measures 0.9″ × 0.9″, has a typical efficiency of 85% to 95%, and can supply typical continuous output currents between 2 A and 4 A depending on the input voltage. The regulator also features reverse voltage protection and an optional enable input that can be used to put the regulator in a low-power state with a current draw of less than 10 µA per volt on VIN.

Notes:

1

Without included optional headers or terminal blocks. Height with terminal blocks installed is approximately 0.5″.

2

Without included optional headers or terminal blocks.

3

Typical continuous output current at 5 V in. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation. See the output current graph under the description tab for more information.

4

To -20 V. Connecting supplies over 20 V in reverse can damage the device.

5

While enabled with no load. Typically the quiescent current is much lower (under 20 mV). See the quiescent current graph under the description tab for more information. Can be reduced to under 1 mA using the enable pin.
