ITEM NAME:SS56 Automatic Step-Up And Step-Down Power Supply Voltage Regulator Module 5U2R2 SS56 Automatic Step-Up And Step-Down Power Supply Voltage Regulator Module 5U2R2 Automatic step-up buck power supply module adjustable voltage 0.5-30V power supply buck and boost 4A.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. Wide voltage input 5.5-30V, wide voltage output 0.5-30V, both boost can also buck, such as you adjust the output voltage of 18V, then the input voltage between 5.5-30V casually change, will be constant output 18V; and then you Input 12V, adjust the potentiometer to set 0.5-30V arbitrary output; high power, high efficiency, better performance than XL6009 / LM2577 program. 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 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;Finally, XL6009 / LM2577 program is low efficiency, ordinary inductive heat, not the buck chip, the lack of adequate protection. Introduction:High power, high efficiency, better performance than XL6009 / LM2577 program. Using external 60V75A high power MOS, parallel high current high withstand voltage Schottky diode SS56. Not 6009 or 2577 program SS34 can be compared, because according to the principle o.Introduction:High power, high efficiency, better performance than XL6009 / LM2577 program. Iron silico aluminum magnetic ring inductance.
