LM2596S DC-DC step-down power supply module 3A adjustable step-down voltage regulator module super LM2576 -62672

1. Input voltage: 3.2V~46V (recommended for use within 40V)

2. Output voltage: 1.25V~35V

3. Output current: 3A (maximum)

4. Conversion efficiency: 92% (maximum)

5. Output ripple <30mV

6. Switching frequency: 65KHz

7. Working temperature: -45°C~ +85°C

8. Dimensions: 43.2mm * 21.0mm * 14.0mm (length * width * height)

Wiring:

• IN+ input positive IN- input negative

• OUT+ output positive OUT-output negative

1. Input voltage range: DC 3.2V to 40V (The input voltage must be 1.5V higher than the voltage to be output. It cannot be boosted.) Features:

2, the output voltage range: DC 1.25V to 35V voltage continuously adjustable, high efficiency (maximum 92%) maximum output current is 3A.

Module Usage:

1. Connect to the power supply (3-40V), the power indicator light is on, and the module works normally.

2. Adjust the blue potentiometer knob (generally rotate the boost clockwise, counterclockwise to step down) and use a multimeter to monitor the output voltage to the required voltage.

Requires Attention:

Long-term work is recommended to use current within 2.5A, plus heat sink (10W output or more); because it is a step-down module, in order to ensure output stability, please maintain a minimum 1.5V differential pressure.

LM2596HVS:

Description

Input voltage: 4.5-50V,

the volume of L 40 * W 21.5 * H 13.5mm (including potentiometers).

Input: IN+ input positive IN- input negative

Output: OUT+ output positive OUT- output negative

Adjustment method: first correct input power (between 4.5-50V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise),

Output voltage: (3-35V) continuously adjustable (recommended load debugging).

Minimum pressure: 1.5V

Output current: rated current 2A, 3A maximum

Output Power: 15W maximum

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

Static power consumption is only about 6mA.

Connection: Welding, plus pin can be directly soldered after the PCB.

Operating temperature: Industrial grade (-40 to + 85 degrees Celsius)

Load regulation: ± 1%

Voltage Regulation: ± 0.5% (mean time to achieve no-load output voltage will be higher, but as long as there is with 1MA load, the output voltage will be normal, does not affect the functionality, ease of use.)

Short circuit protection: current limiting, thermal protection, self-recovery.
