Brand: QSKJ
Model: QS-0524CBDE-15W
Features:
The new original XLSEMI chip, eliminate fake, disassemble chip.
Imported SMD electrolytic capacitors, not accompanied by homemade capacitance.
Up to 400Khz operating frequency, and LC filter circuit, output ripple is very low.
Import TDK inductors, the heat and noise to a minimum.
Input and output three MLCC Multilayer ceramic capacitors, interference enhance stability.
PCB use kb of A grade sheet material, to prevent cardboard, garbage plate.
Built-in MOSFET, the LM2577 built-triode say goodbye, can reach 94% efficiency.
Increased enable the port, you can control whether the boost circuit.
