Input Voltage (V_IN):
- Ensure the input voltage is within the range of 4.5V to 20V to prevent damage to the device.
Output Voltage (V_OUT):
- Adjust the output voltage using external resistors as per the datasheet recommendations. The adjustable range is from 1.2V to 5V.
Output Current (I_OUT):
- The device can supply a continuous current up to 3A. Ensure proper heat sinking if operating near maximum current.
Switching Frequency (f_SW):
- The switching frequency is fixed at 1.5MHz. This value cannot be adjusted externally.
Efficiency (η):
- Optimal efficiency is achieved at an input voltage of 5V and an output current of 1A. Efficiency may vary with different load conditions.
Quiescent Current (I_Q):
- The quiescent current is typically 60μA. Ensure this is accounted for in low-power applications.
Dropout Voltage (V_DO):
- At an output current of 1A, the dropout voltage is approximately 1.2V. Consider this when designing the power supply circuit.
Operating Temperature (T_OP):
- The device is designed to operate within a junction temperature range of -40°C to 125°C. Ensure adequate thermal management for reliable operation.
Storage Temperature (T_STG):
- Store the device in environments where the temperature ranges between -65°C and 150°C to maintain its integrity.
