LM2596S DC-DC Adjustable Digital Regulated Voltage Module Converter LM2596S

Features:

With voltage meter display,voltage meter error of±0.1V, the range of 0~40V. (note: to ensure that the voltage meter accuracy, please make sure that the input voltage is 4V or more).
Low light touch button switch measurement input or output voltage, and a light show is voltage measurement which road, and keep the last set, even if the power switch on again.
Voltmeter fine-tuning: hold down the button about 1-2S into fine-tuning mode, can remove button on the calibration at this time. (please do not use standby function, usually).
Long press to touch the button for 3 seconds can shut down LED display, touch again, key can open the LED display.
Input voltage:4V~40V
Output voltage adjustable range1.25V~37V adjustable (input voltage must be higher than the output voltage is about 1.5V).
Maximum output current can be as high as 3A, normal and stableworking current in 2A.
Low the internal oscillation frequency, 150KHZ belong to the second generation of switch voltage regulator, low consumption, high efficiency.
