LM2596S DC-DC Step Down Module Adjustable LM2596 Constant Current Voltage

Description

Input voltage: 7-35V

Output voltage: 1.25-30V adjustable

Dropout voltage: input voltage must be higher than output voltage of 2V

Output current: 0-3A, 3A maximum

Output power: 15W(If the temperature is high, please strengthen heat dissipation)

Conversion efficiency: 92% maximum (the higher the output voltage, the higher the efficiency)

Turn lamp current: constant current value * (1% -100%), turn lamp current and constant current value linkage, such as constant current value is 3A, turn the lamp current is set to 0.1 times that of the constant current (0.1 * 3 A = 0.1A), when the value of the constant current regulation into 2A, turn lamp current is 0.1 times that of the constant current (0.1 * 2A = 0.2A). The default shipment has to adjust to the 0.1 times

Indicator light:

constant current cc indicator light red,

charging indicator light red,

full-charged indicator light blue

The output ripple: 20M bandwidth (for reference only)

Input 12V output 5V 3A 60mV (MAX)

Working temperature: industrial grade (- 40 — 85 celsius degree) (when temperature is more than 40 degrees, please reduce power, or enhance heat dissipation)

Full load temperature rise: 45 celsius degree

No-load current: 10mA typical (12V to 4.2V)

Load regulation: ± 1%

Voltage regulation: ± 0.5%

Dynamic response speed: 5% 200uS

Output short circuit protection: yes, constant current (current setting constant current value)

Connection mode: can lead directly welding on the PCB
