ΠΕΡΙΓΡΑΦΗ

These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can typically be as high as 5 A. This regulator is available with a fixed 5V.

ΕΠΙΠΛΕΟΝ ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ

  • Input voltage: 2.9V to VOUT
  • Fixed: 5V output with 4% accuracy
  • 5A switch allows for input currents up to 5A
  • Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and under-voltage lockout
  • Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load
  • Two mounting holes for #2 or M2 screws
  • Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board

ΣΥΝΔΕΣΜΟΛΟΓΙΑ

This boost regulator has four connections: input voltage (VIN), ground (GND), and output voltage (VOUT), and ENABLE.

 

 

The input voltage, VIN, must be at least 2.9 V and should not exceed the output voltage, VOUT. (If VIN is higher than VOUT, the higher input voltage will show up on the output, which is potentially dangerous for your connected load and could also damage the regulator.)

The regulator is enabled by default: a 100 kΩ pull-up resistor on the board connects the ENABLE pin to reverse-protected VIN. The ENABLE pin can be driven low (under 0.7 V) to put the board into a low-power state. The quiescent current draw in this sleep mode is dominated by the current in the pull-up resistor from ENABLE to VIN and by the reverse-voltage protection circuit, which will draw between 10 µA and 20 µA per volt on VIN when ENABLE is held low. If you do not need this feature, you should leave the ENABLE pin disconnected. Note that like most boost regulators, the input power will pass through to the output when the board is disabled, so the ENABLE pin cannot be used to turn off power to the load.
