DC-DC Step Up Down Step-Up Power Supply Module Converter Voltage Adjustable USB
#1 Step Up Module
Description:The reverse voltage module MC34063A_NV is a chip based MC34063A for providing reverse voltage, negative voltage modules. It is capable of converting the 5V voltage to a voltage output of -5V. The output voltage can be adjusted by adjusting the potentiometer as required.
Features:
1. Using embedded technology of single chip microcomputer.
2. Input a positive voltage and output a negative voltage.
3. Easy to operate, the output voltage can be adjusted by a potentiometer.
4. The module is small, easy to carry and use in various occasions.
5. The IC internal switch tube of this module is 1.5A, but for safety and heat generation, the load power consumption of this module is recommended to be less than 0.5W.
Specification:Input voltage range: 3.6V-36V
Output voltage range: Negative 1.5V to negative 36V
Output voltage regulation characteristics; load regulation rate is less than 5%
Output current: The IC internal switch tube of this module is 1.5A, but for safety and heat generation, the load power consumption of this module is recommended to be less than 0.5W. That is, when the output is negative 5V, the load is within 100MA, and it is recommended to be 50MA.
