DC-DC Boost Buck Module, 5V-30V to 5V-30V Voltage Step-up Step-down Converter 35W 3A CC CV Module Board

• [Stable Performance] - This boost/buck module can step up or step down voltage and maintain a stable output voltage.
• [Protect Function] - It supports input over-current protection, input under-voltage protection and MOS input anti-reverse protection.
• [Specification & Application] - It has quite low output ripple voltage, for example, 20mV when output is 12V 3A, which is great for powering speaker, audio amplifier, artificial circuit, etc.
• [Easy to Use] - Input 5V to 30V and it can charge storage battery, lithium battery, AA rechargeable battery, or adjust constant current LED brightness.
• [NOTE] - Red&blue light on when constant current charging, blue light on only when constant voltage charging, blue&green light on when almost fully charged, green light on only when fully charged.

Description: This DC-DC converter module is a buck (step-down) converter combined with a boost (step-up) converter whose output voltage can be lower or higher than the input. It is characterized by small size, high power, high efficiency and stable performance. It would maintain output voltage stability when input voltage is higher, lower than output voltage. It would maintain the stability of the output voltage when the input voltage is higher than the output voltage , Specifications: Input voltage: 5V ~ 30V Output voltage: 0.5V ~ 30V Output current: 3A (or 4A, if the heat dissipation is improved) Output power: 35 W (or 60 W when heat dissipation is improved) Output ripple voltage: 20mV (at 12V 3A output) Conversion efficiency: 87 ~ 91% (increase); 87 ~ 89% (descend) Input overcurrent protection: 10A fuse Input anti reverse protection: High efficient MOS Input undervoltage protection: Yes Overcurrent protection at the output: Yes Frequency: 180 kHz Size: 69 * 28 * 21mm / 2.71 * 1.1 * 0.82 " Package contents: 1 x module
