This module is a LM2577 DC-DC Automatic Buck or Boost Converter 3-35V to 2.2-30V LM2596 Voltage Step-Down Power Supply. IN+ is for positive voltage input. IN- is for negative voltage input. That means after you set the output voltage, it can output your desired voltage no matter the input voltage is LESS or GREATER than your desire voltage. Step-up or Step-down action is automatic.

Specification: Module properties: Non isolated, Automatic Buck-Boost (SEPIC) Rectifier type : Non synchronous rectifier Input voltage : 3V-35V Output voltage: 2.2V-30V Output current: 2A MAX Conversion efficiency: 92% ( max) Switching frequency: 50KHz Output ripple : 40mV MAX Load regulation rate: ± 0.5% Voltage regulation rate: ± 0.5% Working temperature: - 40 ° C to +85 ° C Dimension: 48 x 24 x 14mm

Application: Great for solar panel supply, solar panel input voltage is not constant. Therefore it can output constant voltage
