Features:
★ The module uses the domestic high-quality LM2596 chip, which has high efficiency (92%) and low heat generation. It can easily reach a current above 3A. At the same time, it cooperates with the original TI op amp to control the output current, making the overall output very stable.
★ This module uses original Sanyo filter capacitor with low ESR, which can make the ripple voltage as low as 50mV!
★ This module uses machine patch, reflow soldering, and each module undergoes two hours of aging test before shipment to ensure high reliability.
★Charging lithium-ion battery: When the lithium-ion battery is at a relatively low voltage, if it is directly charged with a constant voltage, the charging current will be too large due to the large voltage difference, which will cause the battery to be damaged. Current charging, when charging to a certain level, it will automatically switch back to constant voltage charging.
