300W 20A DC-DC Buck Converter Step-down Module Constant Current

Features

1. Scope: High-power LED constant current driver, rechargeable lithium batteries 4V, 6V, 12V, 14V, 24V battery charging; nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators.
2. Output voltage: continuously adjustable (1.25-36V) (applied to the input voltage is higher than the output voltage applications can boost).
3. Turn lights Current: current value * (0.1), turn the lamp current, and constant value linkage, such as the constant value of 3A.
4. Turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).
5. This version is a fixed 0.1 times (actually turn the lamp current value is probably not very accurate) is full of instructions for charging.
6. Minimum pressure: 1V.
7. Output Ripple: about the ripple 50mV (without noise) 20M bandwidth (for reference) Input 24V Output 12V 5A measured.
8. Operating temperature: -10oC to + 75oC (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation).
