MC34063ACN Typical application Circuitry

MC34063ACN

The MC34063ACN is an integrated circuit designed as a versatile switching regulator, used for efficient voltage conversion in a variety of electronic applications.

Application Areas: The MC34063ACN is widely used in DC-to-DC converters, power supply modules, battery chargers, and electronic devices in consumer electronics and automotive systems.

Key Characteristics: It supports a broad input voltage range and can be configured in various modes, including step-up (boost), step-down (buck), and voltage-inverting configurations. The chip also features current limiting and thermal shutdown protection.

Circuit Design Example – Mobile Device Charger:

1. Input Voltage Source Connection: Connect a power source (such as a 5V USB input) to pin 1 of the MC34063ACN. This chip's wide input voltage range is ideal for USB-powered applications.

2. Switch Collector Configuration: Pin 2 of the MC34063ACN, the switch collector, should be connected to an inductor, integral to the charging circuit's step-up configuration.

3. Switch Emitter Grounding: Connect pin 3, the switch emitter of the MC34063ACN, to the circuit's ground. This grounding is crucial for stable operation.

4. Voltage Feedback Network: Pin 4 of the MC34063ACN is connected to a feedback network to regulate the charger's output voltage.

5. Ground Pin Connection: Ensure that pin 5 of the MC34063ACN is connected to the common ground of the circuit.

6. Timing Capacitor Setup: Attach a timing capacitor to pin 6 of the MC34063ACN. This capacitor determines the regulator's switching frequency.

7. Driver Collector to External Components: Pin 7, the driver collector of the MC34063ACN, connects to external components like a transistor or diode in the charging circuit.

8. Driver Base Connectivity: Utilize pin 8 of the MC34063ACN to connect the driver base, which is part of the external switch mechanism in the charger.

Design Considerations: When creating a circuit with the MC34063ACN, factors such as the input voltage range, desired output voltage, load requirements, switching frequency, and appropriate selection of the inductor and diode should be considered. Configuring the feedback network correctly and managing thermal aspects are also essential.

In summary, the MC34063ACN is crucial in applications like mobile device chargers, where efficient and adaptable voltage conversion is required. Designing this circuit involves meticulous attention to input-output specifications, component selection, feedback network arrangement, and thermal management for optimal functionality.
