Description
Introduction
1: The new original XLSEMI chip, eliminate fake, disassemble chip.
2: Imported SMD electrolytic capacitors, not accompanied by homemade capacitance.
3: Up to 400Khz operating frequency, and LC filter circuit, output ripple is very low.
4: Import TDK inductors, the heat and noise to a minimum.
6: Input and output three MLCC Multilayer ceramic capacitors, interference enhance stability.
7: PCB use kb of A grade sheet material, to prevent cardboard, garbage plate.
8: Built-in MOSFET, the LM2577 built-triode say goodbye, can reach 94% efficiency.
9: Increased enable the port, you can control whether the boost circuit.
10: Dimensions: 49 (L) * 23.4 (W) * 11.4 (H) mm (excluding potentiometer)
