Wide Input DC-DC buck-boost automatic adjustable constant voltage current power supply module charger Constant voltage constant current description The ... morefigure is a schematic diagram. The actual circuit with transistors Q instead of the switch S. Q transistor controlled by the chip to its switching state. The switching times per second(the oscillation frequency) between 0-500000(500K) times the oscillation frequency can be raised to accelerate the voltage control transistor Q chip through oscillation to stabilize the output frequency voltage(constant voltage) According to the formula I = U/ R(current = voltage ÷ resistance) The output voltage of the chip can be stabilized by adjusting the output current(constant current) When the load resistance R changes according to the formula R = U/ I know. Constant current constant voltage is not present, is a violation of science. Therefore. Constant voltage constant current means: constant voltage or constant current between choose one. Power Description Line heating formula P = I ^ 2* R(= square of current heat resistance* The line resistance is fixed, and only the heating current on the line, the line is the maximum current capability 5A. Power formula is P = UI(power = voltage* current) Input 12V, maximum input power is 12V* 5A = 120W. When you enter 60V. Maximum input power is 60V* 5A = 300W. Parameter Input voltage: DC 10-60V Output voltage: DC 10-80V Input Current: 5A The following restrictions are not adjustable. Adjustable output current:1-5A Output current: Input voltage Input current × ÷ output voltage ×(conversion efficiency of 92-98% =? Input power: up to 60V* 5A = 300W Output power: slightly lower than the input power Conversion principle: voltage × current = voltage × current. For example: 24V × 6A = 48V × 3A, pay attention!
