This module is different from the LM2596 and XL4005 step-down
modules on the market, whose chip design power is 15W and 50W
respectively. This step-down module in our shop uses the original
authentic upgraded chip, which is superior to similar products in
input and output voltage range, output power and efficiency. The
power can reach 75W, with a very high cost performance. Module
highlights: 5A high power high efficiency low ripple strip power
indicator light free heat sink!!! Module performance and characteristics: Module nature: Non-isolated step-down module (BUCK) Input voltage:
4-38V (Input please try not to exceed 38V) Output voltage: 1.25-36V
continuously adjustable Output current: 0-5A, recommended for use
within 4.5A Output power: Recommended for use within 75W. Operating
temperature: -40~+85 degrees Operating frequency: 180KHz Conversion
efficiency: up to 96% (efficiency is related to input, output
voltage, current and differential pressure) Load adjustment rate: S
(I) ≤0.8% Voltage adjustment rate: S (u) ≤0.8% Power indicator: Yes
Short circuit protection: have (limited current 8A) Overtemperature
protection: there is (automatically shut off output after
overtemperature) Input backconnection protection: none (if
necessary, please insert high current diode in the input string)
Installation: 2 3mm screws Connection mode: Welding, with V-IN as
input and V-OUT as output Module size: 54mm long, 23mm wide, 18mm
high Weight: 16g Scope of application: This module can be used in the input voltage is higher than the
output voltage of the step-down field, such as battery, power
transformer, DIY adjustable voltage regulator power supply, 24V
vehicle pen meter this power supply, industrial equipment
step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to
24V, etc. Please pay attention to: Some customers reflect that the module output voltage can not be
adjusted, always equal to the input voltage. When you encounter
this problem, please rotate the potentiometer counterclockwise more
than 10 laps, and then use the module can adjust the voltage
normally. Because when the step-down module leaves the factory, the
default output voltage is about 20V.
