Instructions for Using the MC34063AP1G
Input Voltage (VIN):
- The input voltage can range from 3.0V to 40V. Ensure that the input voltage is within this range to avoid damage to the device.
Output Voltage (VOUT):
- The output voltage can be set using external components such as resistors and capacitors. The minimum output voltage is 1.25V, and the maximum is 40V.
Switching Frequency (fSW):
- The switching frequency can be adjusted by selecting appropriate values for the timing resistor (RT) and capacitor (CT). For example, with RT = 10kΩ and CT = 100pF, the typical switching frequency is 35kHz.
Maximum Switch Current (ISW):
- The maximum switch current is 1.5A. Ensure that the load does not exceed this limit to prevent damage to the device.
Quiescent Current (IQ):
- The quiescent current is typically 3.5mA when the input voltage is 5V and the output voltage is 5V. This current is the power consumed by the device when it is operational.
Shutdown Current (ISD):
- When the shutdown pin (SHDN) is grounded, the device enters a low-power mode, and the shutdown current is typically 0.1μA. Use this feature to conserve power when the device is not in use.
Thermal Shutdown (TSD):
- The device has thermal protection and will shut down if the temperature exceeds 160°C. Ensure proper heat dissipation to prevent thermal shutdown.
Operating Temperature (TOPR):
- The operating temperature range is from -40°C to 85°C. Ensure that the device operates within this temperature range for reliable performance.
Storage Temperature (TSTG):
- The storage temperature range is from -65°C to 150°C. Store the device in a temperature-controlled environment to ensure its longevity.
Additional Notes:
- Always refer to the datasheet for detailed information and specific application circuits.
- Use appropriate external components (resistors, capacitors, inductors) to configure the device for your specific application.
- Ensure proper PCB layout and grounding to minimize noise and improve performance.
