CV/CC Adjustable Automatic Buck Boost Power Module

Product Information:

The XL6009/LM2577 on the market uses a single SS34 rectifier tube, and the withstand voltage value is not enough. According to the buck-boost principle, the withstand voltage value of the rectifier tube and the switch tube should be greater than the maximum input voltage and increase the sum of the output voltage (if the input voltage and output voltage are mostly 30V , the withstand voltage value of mos tube and Schottky should reach at least 60V), SS34 withstand voltage is 40V high, 6009 high withstand voltage 36V, the design of this module has potential safety hazards;

Secondly, the current output capacity is not enough, the original SS34 high current is 3A (plus the switching loss, the heat dissipation is not good, the real current capacity is less than 3A), once the Schottky voltage is too high or the temperature is too high, it will be broken down and burned. The main chip has security risks;

Finally, the XL6009/LM2577 solution has low efficiency, and the common inductor generates a lot of heat. It is not a buck-boost chip and lacks sufficient protection.

This module uses a buck-boost chip as the main controller, an external 60V 75A MOS tube as a switch tube, and dual 60V 5A SS56 Schottky for rectification; XL6009/LM2577 scheme, 30V input and output voltage and 3A high current are not enough to withstand Live the scrutiny of the principle and the real textual research! gWmWivOiz9St5JW/ZAY9YKKiVq95BW3I68CL

Introduction: Wide voltage input 5-30V, wide voltage output 0.5-30V, both boost and buck. For example, if you adjust the output voltage to 18V, then the input voltage will be constant between 5-30V and 18V will be output constantly; For example, if you input 12V, adjust the potentiometer to set any output from 0.5-30V.

High power, high efficiency and better performance than XL6009/LM2577 solution. The external 60V75A high-power MOS is used, and the high-current and high-voltage Schottky diode SS56 is connected in parallel. It is not comparable to the SS34 of the 6009 or 2577 scheme, because according to the buck-boost principle, the withstand voltage of MOS and Schottky is greater than the sum of the input and output voltages.

FeSiAl magnetic ring inductor, high efficiency. No inductive whistling in constant current mode.

The current size can be set for limiting output current, constant current driving, and battery charging lights.

With its own output anti-backflow function, there is no need to add an anti-backflow diode when charging the battery.
