DC-DC преобразовател понижаващ с Lm2596
ПЪЛНО ОПИСАНИЕ:
This module can be used in fields where
the input voltage is higher than the step-down output voltage, such as
batteries, power transformers, DIY adjustable power supplies, 24V
automotive step-down in the power equipment industry, 12V switch 3.3V,
12V switch 5V, 24V to 5V, 24V Turn 12V, 36V turn 24V and so on.
parameter:
Product size: 66mm * 36mm* 14mm (length x width x height)
Touch the button to switch the input or output voltage measurement, and there is a light to display the voltage being measured,
And save the settings, and even power off and on again.
The input voltage is 4.5~40V. (The input voltage must be higher than the output voltage by more than 1.5v)
The
adjustable output voltage range is 1.25V～37V continuously adjustable.
(The input voltage must be higher than the output voltage 1.5V)· The output current is 3A, and it is recommended to use it within 2.0A. Large current is required to enhance heat dissipation.
· The output power is 20W, 15W, please strengthen the heat dissipation.
· High conversion efficiency, an average of 88% (efficiency is related to input and output voltage, current, and pressure)
· With reverse polarity protection, reverse polarity does not burn
usage:
The
on-board voltmeter displays the output voltage. Press and hold the
right button for 2 seconds and then release. The voltmeter and the
output voltage indicator "OUT" will flash simultaneously, and the output
voltage adjustment mode will be entered; for the same reason, when the
voltmeter displays the input voltage, long Press the Right button for 2
seconds and then release it, the voltmeter and the input voltage
indicator "IN" will flash synchronously, and then enter the input
voltage adjustment mode;Touch
the right button to increase the voltage by one unit, and touch the
left button to decrease the voltage by one unit; because the voltage is
less than the unit value of 0.1V, you need to press 1-5 times to see the
0.1V change of the voltmeter, according to the current display Press
the voltage value of, the higher the current display voltage, the fewer
the number of presses;After
the voltage is adjusted, press and hold the right button for 2 seconds
and then release it to exit the voltage calibration mode, and all
parameters are set to be automatically power-off and saved.·Note:
In this way, you only need to adjust and calibrate once to obtain the
accurate voltage value in the entire voltage range. This function is
designed to meet your requirements and design higher accuracy and ease
of use.
notes:
1.
When the output voltage of the module cannot be adjusted, the output
voltage is always equal to the input voltage. Please adjust the
potentiometer counterclockwise for more than 20 turns. (Let the
potentiometer lean against your chest and turn counterclockwise to
boost).2. The input voltage must be higher than the output voltage by more than 1.5v
3. Need high current or high power to enhance heat dissipation
