Boost Converter Circuit Using Mc34063 Ic

We can use it as a buck converter a boost converter or an inverter.

Boost converter circuit using mc34063 ic. How to build a square to triangle wave converter circuit how to build a square to sine wave converter circuit how to build a clock circuit with a 555 timer how to build an astable multivibrator circuit with transistors. Where to use mc34063. Mcp34063 can be configured in three operation buck boost and inverting we use mc34063 as switching boost regulator and will boost 3 7v lithium battery voltage to 5 5v with 500ma output current capabilities. It is a dc dc converter chip.

So we can use mc34063 ic which is the most popular switching regulator in such applications. Mc34063a is ideal for small projects which need dc to dc converters. The circuit that i am gonna show here will step up the voltage into 3 different level like 5v 5 3v 6v. In the previous tutorials we demonstrated detailed design of 3 7v to 5v boost converter using mc34063 and 12v to 5v buck converter using mc34063 today we will use the same mc34063 ic to build a dc to dc boost converter circuit which can convert small voltage like 3v to higher voltage upto 40v.

It requires a minimum number of external components for operation. In the previous tutorial we demonstrated detailed design of boost converter using mc34063 where a 3 7v to 5v boost converter was designed here we see how to convert 12v to 5v as we know that exact 5v batteries are not always available and sometimes we need higher voltage and lower voltage at the same time to drive different parts of circuit so we use higher voltage 12v source as the main. The mc34063 is a very useful chip. Functional block diagram the reference voltage is set at 1 25 v and is used to set the output voltage of the converter.

A sample mc34063a circuit diagram for buck and boost circuit using the mc3463a ic is shown below. A lot of choices available in this segment. The ic mc34063 is contains all the primary circuitry needed for building simple dc dc converters. In the above two circuits the boost converter is designed to convert 12v to 28v with a current rating of 125ma and the buck converter is used to convert 25v to 28v with a current rating of 500ma.

And this is a classic switch mode power supply using the mc34063 chip to act as a step up or boost converter. Boost converter circuit using mc34063 ic is designed with few external components and this ic is suitable for compact dc dc boost converter circuit. A short circuit fault protection circuit is integrated inside chip. The important element of the circuit is boost converter ic.

Mc34063 is most popular switching regulator in such segment. There are also options to limit the output current. The mc34063 was designed to be incorporated in buck boost or voltage inverter converter applications. Use ic mc34063 so easy circuit adjustable vr1 for control efficiency at 12v 600ma.

We have previously built buck converter circuit to step down the voltage. All these functions are contained in an 8 pin dip or soic package. Ic mc34063a takes an input signal in a range of 3 0v to 40v and gives an adjustable output voltage and output current of up to 1 5a.
