Dettagli
This step-down (buck) regulator generates a fixed 5 V output from input voltages up to 38 V. It is a switching regulator
(also called a switched-mode power supply (SMPS) or DC-to-DC converter) and has a typical efficiency between 85% to 95%.
The available output current is a function of the input voltage and efficiency (see the Typical Efficiency and Output Current section below), but the output current can typically be as high as 5 A. The regulator has a typical quiescent current draw of less than 1 mA, and the ENABLE pin can be used to put the board in a low-power state that reduces the quiescent current to approximately 10 µA to 20 µA per volt on VIN.
Features:
-Input voltage: 6 V to 38 V (see below for more details on the regulator’s dropout voltage, which affects the low end of the operating range)
-Fixed 5 V output (with 4% accuracy)
-Typical maximum continuous output current: 5 A
-Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, soft-start, and under-voltage lockout
-Typical efficiency of 85% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
-700 µA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
-Compact size: 0.7? × 0.8? × 0.35? (17.8 mm × 20.3 mm × 8.8 mm)
-Two 0.086? mounting holes for #2 or M2 screws
