Boost Buck Step Up-Down Automatic Converter

Descripción:
This is a powerful, efficient step-up (boost) and step-down (buck) switching voltage converter.
It will automatically change between boosting and bucking to maintain a stable output voltage, regardless of the input.
The output is set with a multi-turn potentiometer.

Boost Buck Step Up-Down Automatic Converter features:

- IC Chip: LM2577S-ADJ  and  LM2596S-ADJ
- Module Properties: non-isolated Boost Buck constant current, constant voltage module (CC CV) charging module
- Scope: High-power constant current LED driver.
- Battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind generators.
- Solar Panel, Wind generator voltage regulator, Car Power Supply.
- Input voltage: 4-35V
- Output voltage: 1.25-25V
- Output Current: Rate 3A ( If more than 15W, please install the heat sink, this item do not include heat sink)
- Constant current range:0-2A (adjustable)
- Revolving light current: constant current value * (1% -100%), The constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A =    0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
- Output power: natural cooling 15W, (if install heat sink can be 25W)
- Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency
- Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation)
- Full load temperature rise: 45°c
- This Converter only can rise Voltage, it can not rise Power.
- If use Solar as power supply, please make sure the input power is 1.1 times than the output power.
- Dimensions: 48 x 38 mm
