On the surface, XL6009/LM2577 uses a single SS34 rectifier tube. Firstly, the voltage withstand value is not enough. According to the principle of voltage rise and fall, the voltage withstand value of the rectifier tube and switch tube should be greater than the sum of the maximum input voltage and the maximum output voltage (if the maximum input voltage and output voltage are both 30V, the voltage withstand value of the MOS tube and  tube should be at least 60V). SS34 can withstand up to 40V, while 6009 can withstand up to 36V. The design of this module poses a safety hazard;
Secondly, the current output capacity is insufficient. The maximum current of the original SS34 is 3A (coupled with switch losses, poor heat dissipation, and the actual current passing capacity is less than 3A). Once the voltage or temperature of the  is too high, it will be broken down, which will burn out the main chip and pose a safety hazard;
Finally, the XL6009/LM2577 scheme has low efficiency, high heat generation from ordinary inductors, and is not a voltage regulator chip, lacking sufficient protection.
This module uses a voltage regulator chip as the main controller, an external 60V 75A MOSFET as the switching transistor, and dual 60V 5A SS56  for rectification; The XL6009/LM2577 scheme, with an input and output voltage of 30V and a large current of 3A, cannot withstand the scrutiny of principles and practical verification!
Introduction: With a wide voltage input of 5-30V and a wide voltage output of 0.5-30V, it can increase or decrease voltage. For example, if you adjust the output voltage to 18V, the input voltage can vary from 5-30V to a constant output of 18V; For example, if you input 12V, adjust the potentiometer to set it to 0.5-30V for any output.
High power, high efficiency, and better performance than the XL6009/LM2577 scheme. Adopting an external 60V75A high-power MOS, coupled with a high current and high voltage  diode SS56. It is not comparable to SS34 in 6009 or 2577 schemes, because according to the principle of voltage rise and fall, the withstand voltage of MOS and  is greater than the sum of input and output voltages.
Iron silicon aluminum magnetic ring inductor, high efficiency. There is no inductive whistling sound in constant current mode.
The current size can be set for limiting output current, constant current drive, and battery charging lamp applications.
Equipped with output anti backflow function, there is no need to add an additional anti backflow diode when charging the battery.
