Instructions:

1. Input Voltage (V_IN): Ensure the input voltage is within the specified range (100V to 375V) to avoid damage or improper operation.
2. Output Voltage (V_OUT): The typical output voltage is 5V. Use appropriate feedback components to maintain this voltage.
3. Output Power (P_OUT): The maximum continuous output power is 35W. Do not exceed this limit to prevent overheating.
4. Switching Frequency (f_SW): The nominal switching frequency is 132kHz. This can be adjusted using external components if needed.
5. Quiescent Current (I_Q): The quiescent current is typically 1.5mA. This is the current drawn by the device when no load is applied.
6. Efficiency (畏): The typical efficiency at full load is 85%. Ensure proper heat dissipation to maintain this efficiency.
7. Standby Power (P_SB): The standby power consumption is typically 0.3W. This is the power consumed when the device is in standby mode.
8. Operating Temperature (T_OP): The operating temperature range is -40掳C to 85掳C. Ensure the device operates within this range to avoid thermal stress.
9. Storage Temperature (T_STG): The storage temperature range is -65掳C to 150掳C. Store the device in a suitable environment to prevent damage.
10. Junction Temperature (T_J): The maximum junction temperature is 150掳C. Monitor the temperature to prevent overheating.
11. Thermal Resistance (R_TH): The junction-to-ambient thermal resistance is 45掳C/W. Use heatsinks or other cooling methods as necessary.
12. Input Capacitance (C_IN): A recommended input capacitance of 1渭F helps filter input ripple.
13. Output Capacitance (C_OUT): A recommended output capacitance of 220渭F helps stabilize the output voltage.
14. Maximum Load Current (I_MAX): The maximum continuous output current is 7A. Ensure the load does not exceed this value.
15. Minimum Load Current (I_MIN): The minimum load current for stable operation is 0.1A. Ensure a minimum load is present.
16. Overvoltage Protection (OVP): The overvoltage protection threshold is 110% of the nominal output voltage. This protects against excessive output voltage.
17. Overcurrent Protection (OCP): The overcurrent protection threshold is 120% of the nominal output current. This protects against excessive load.
18. Short-Circuit Protection (SCP): The device has automatic recovery from short-circuit conditions to prevent damage.
19. Under-voltage Lockout (UVLO): The under-voltage lockout threshold is 80V. The device will shut down if the input voltage falls below this level.
20. Soft-Start Time (t_SS): The typical soft-start time is 200ms. This helps reduce inrush current during startup.
21. Package Type: The device is available in a Dual Inline Package (DIP). Ensure the package is suitable for your application.
