Description:
1. Can be boosted, but also buck, the output voltage 0.5-30V arbitrary adjustment, limiting current 0-4A arbitrary adjustment; can be used for LED constant current drive, battery charging and other constant current occasions, while limiting current with overcurrent protection, more secure ; Constant current mode indicator, charging indicator, full of light. Output anti-backwash, do not charge the battery when the additional anti-flooding diode.
2. XL6009 / LM2577 on the market using a single SS34 rectifier, the first pressure value is not enough, according to the principle of starting and lowering the rectifier and switch tube voltage value is greater than the maximum input voltage plus the maximum output voltage (if the input voltage and output voltage are the largest For the 30V, mos tube and Schottky's voltage at least to reach 60V), SS34 pressure up to 40V, 6009 maximum pressure 36V, this module design is the existence of security risks;
3. The current output capacity is not enough, the original SS34 maximum current 3A (coupled with switching losses, poor heat, the real current capacity can be less than 3A), Schottky once the voltage is too high or the temperature is too high will be broken, Whole module. There are security risks;
4. Finally, XL6009 / LM2577 program is low efficiency, ordinary inductive heat, not the buck chip, the lack of adequate protection.
5. The module uses the step-up and down the chip as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky do rectifier.
Parameter:
1. Input voltage: 5-30V
2. Output voltage: 0.5-30V
