LM2577S - LM2596S Buck-Boost DC-DC Adjustable Step Up-Down Converter v2 - (AD33547)

Description:

This module will automatically adjust the output voltage despite variations in the input voltage; you can adjust the output voltage to the desired level. This module can either step down or step up the output voltage relative to the input. This board is widely used as a voltage regulator in automobiles, solar photovoltaic systems, wind power systems, and other voltage instability applications.

Features:

- Input voltage: 4-35V

- Output voltage: Continuously adjustable (NO load 1.25-25V)

- Output current: 3A maximum (for more than 15W, please install a heat sink)

- CC (Constant Current) range: 0-2A (adjustable)

- Minimum voltage difference: 2V

- Output power: 15W with natural cooling

- Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency)

- Operating temperature: Industrial (-40℃ to +85℃) (ambient temperature above 40℃, lower power usage, or add a heat sink)

- Full load temperature rise: 45℃

- Indicators: CC (Constant Current) indicator is red, charging indicator is red, fully charged indicator is blue

- Output short-circuit protection: Yes, constant current

- Connection method: Can be soldered directly to the PCB with a wire

- Input: IN+ input corresponds to Positive, IN- input is negative

- Output: OUT+ output is positive, OUT- is negative output

- Module size: 50 x 37 x 13mm

Some applications:

- High-power constant current LED driver

- Lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium, nickel-metal hydride

- Solar panels, power supplies, voltage regulator circuits, wind generators, etc.
