3.3V-5V Voltage Regulator Board

3.3V-5V Voltage Regulator Board

Our Price: $18.23


The 3.3V-5V Voltage Regulator Board is an accessory board that will come very useful in all those scenarios where the user needs to convert an input of 3.3V to an output of 5V. This additional board has been smartly equipped with a Step-Up Switching Regulator MC34063A, which makes it perfect for a step-up power regulation. This MC34063A switching regulator supports all the primary functions required for DC-to-DC converters and also avoids any possibility of short-circuit. Receiving 3.3V input voltage and converting it into a stable 5V DC output voltage, the 3.3V-5V REG additional board has the ability to deliver around 250mA maximum output current. This 3.3V to 5V power conversion source is provided with CN1 and CN2 screw connectors. While the 3.3V voltage is supplied through the CN1 screw connector, the CN2 screw connector serves as a medium to deliver 5V voltage.

IC/Module: MC34063A Step-Up Switching Regulator

The MC34063A is a 1.5-A peak boost/buck/inverting switching regulator that features an internal temperature-compensated reference, a comparator, and an oscillator. This monolithic control circuit also has a PWM controller with active current limiting, a driver, and a high-current output switch. Containing all the primary circuitry needed for building simple DC-DC converters, this easy-to-use IC supports a wide input voltage range from 3 V to 40 V. It has an operating temperature range of 0°C - 70°C.

Operating Voltage

The 3.3V-5V Voltage Regulator Board operates on 3.3V power supply only.


The 3.3V-5V Voltage Regulator Board is ideal for most small electronic projects that require power conversion from 3.3V to 5V. Needing minimal external parts to build converters in the boost, buck, and inverting topologies, this low-cost, small-sized board is perfect for use in equipment like industrial monitors, portable blood gas analysers, and cable solutions.
