Instructions for Using VIPER53SPTR-E
Supply Voltage (VDD):
- Ensure the supply voltage is within the specified range of 4.5V to 5.5V to avoid damage or improper operation.
Output Current (IOUT):
- The VIPER53SPTR-E can provide a maximum continuous output current of up to 3.5A. Design your circuit to ensure it does not exceed this limit to prevent overheating and potential damage.
Switching Frequency (fSW):
- The nominal switching frequency is 65kHz. This value helps in designing the external components such as inductors and capacitors for the power supply.
Quiescent Current (IQ):
- The quiescent current is typically 2.0mA. This is the current drawn by the IC when there is no load on the output.
Efficiency (η):
- The typical efficiency is 88%. This indicates how effectively the IC converts input power to output power under normal operating conditions.
Dropout Voltage (VDROPOUT):
- The dropout voltage is typically 1.2V. This is the minimum difference between the input and output voltages required for the regulator to maintain regulation.
Thermal Shutdown (TSD):
- The IC will shut down if the temperature exceeds 160°C to protect against thermal damage. Ensure proper heat dissipation and cooling mechanisms are in place.
Protection Features:
- The VIPER53SPTR-E includes overvoltage, overcurrent, short-circuit, and thermal shutdown protection. These features help in safeguarding the IC and the connected circuitry from various fault conditions.
Operating Temperature (TOPR):
- The operating temperature range is from -40°C to 125°C. Ensure the ambient temperature is within this range to guarantee reliable operation.
Storage Temperature (TSTG):
- The storage temperature range is from -65°C to 150°C. Store the IC in a controlled environment to prevent damage due to extreme temperatures.
Package Type:
- The VIPER53SPTR-E is available in an SO-8 package. Follow standard handling and soldering guidelines for surface mount devices to ensure proper installation and reliability.
By following these parameters and instructions, you can ensure optimal performance and longevity of the VIPER53SPTR-E in your application.
