I have come across an IC that is used in diy Arduino Inverter and this IC is called MC34063 and I wanted to know what this IC is and where it is typically used. So this is note on this IC.
The MC34063 is a DC-DC converter IC that can be configured as a step-up (boost), step-down (buck), or inverting switching regulator. It integrates all the key components needed for basic switching regulation—including an internal temperature-compensated reference, oscillator, comparator, switch, and current limiting circuitry—making it a versatile and compact solution for power supply design.
Key Features:
-
Input voltage range: 3V to 40V
-
Output switch current up to 1.5A
-
Adjustable output voltage
-
Switching frequency up to 100 kHz
-
Low standby current
-
Few external components needed
Typical Applications of MC34063:
-
Boost Converter (Step-Up)
-
Converts a lower input voltage (e.g., 3.7V) to a higher voltage (e.g., 12V).
-
Used in battery-powered applications.
-
-
Buck Converter (Step-Down)
-
Converts a higher input voltage to a lower regulated output.
-
Common in power supplies for microcontrollers or low-voltage ICs.
-
-
Inverting Converter
-
Produces a negative voltage from a positive input (e.g., +12V to -12V).
-
Useful in dual supply analog or op-amp circuits.
-
-
Battery Chargers
-
Used in simple NiMH or lead-acid battery charger circuits due to its flexible topology.
-
-
Power Supplies for Embedded Systems
-
Ideal for powering Arduinos, sensors, and other electronics from various battery sources.
-
-
Solar Powered Projects
-
Converts variable solar input to a stable voltage for charging batteries or running devices.
-
In summary, the MC34063 is a popular, inexpensive, and easy-to-use IC for basic switching regulator designs, often found in DIY power supply circuits and commercial embedded devices.
