Instructions for Use:
Input Connection: Connect the input voltage (VIN) to the input pin of the CXB1441R. Ensure the input voltage is within the specified range (2.7V to 5.5V).
Output Connection: Connect the output pin to the load requiring the regulated 3.3V output. The maximum continuous output current is 1.2A, with a peak of up to 1.5A.
Ground Connection: Ensure a solid ground connection between the input and output circuits to maintain stability and performance.
Capacitors:
- Input Capacitor: Place a 1μF ceramic capacitor close to the input pin to filter out noise and stabilize the input voltage.
- Output Capacitor: Place a 1μF ceramic capacitor close to the output pin to stabilize the output voltage and reduce ripple.
Thermal Management: The device has a typical junction-to-ambient thermal resistance of 45°C/W. Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
Operating Temperature: The device is designed to operate within a temperature range of -40°C to 85°C. Avoid exceeding these limits to prevent damage or reduced performance.
Storage Temperature: Store the device in a dry environment within the storage temperature range of -65°C to 150°C.
Efficiency: The typical efficiency of the CXB1441R is 90% at full load (1.2A). Monitor power consumption and heat dissipation to ensure optimal performance.
Dropout Voltage: The dropout voltage is typically 0.3V at full load. Ensure the input voltage is at least 0.3V higher than the output voltage to maintain regulation.
Quiescent Current: The quiescent current is very low, typically 0.1mA, which helps in minimizing power loss when the load is not active.
By following these guidelines, you can ensure reliable and efficient operation of the CXB1441R.
