Product Description

Überblick

These high-current step-down (buck) regulators generate a fixed 5 V output from input voltages up to 38 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 and efficiency (see the Typical Efficiency and Output Current section below), but the output current can typically be as high as 9 A.

A very similar version of this regulator is available with a typical maximum output current of 6 A. The two versions of the board are difficult to tell apart visually, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels. You should not use the colors of the printing on the tall, cylindrical electrolytic capacitors to differentiate the two versions as these colors are subject to change. We also carry two much smaller versions of this regulator, one with a typical maximum output current of 2.5 A and one with a typical maximum output current of 5 A.

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, and a PG (power good) indicator makes it easy to monitor the state of the main power for your system. The regulator’s output voltage setting can also be lowered by adding an external resistor.

This regulator has built-in reverse-voltage protection, short-circuit protection, thermal shutdown (which typically activates at 160°C), a soft-start feature that reduces inrush current, and an under-voltage lockout that causes the regulator to turn off when the input voltage is below 4.2 V (typical).

Eigenschaften

Input voltage: 5 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); this can be lowered by adding an external resistor between FB and VOUT
Typical maximum continuous output current: 9 A
Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, soft-start, and under-voltage lockout
Typical efficiency of 80% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
800 µA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
"Power good" output indicates when the regulator cannot maintain its set output voltage
Compact size: 1.6" × 0.8" × 0.3" (40.6 × 20.3 × 7.6 mm)
Four 0.086" 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
