Instructions for LM5116MHX/NOPB

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 60V.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted using external components. Refer to the datasheet for specific resistor values.

3. Switching Frequency (fSW):

   • Set the switching frequency by selecting an appropriate resistor value. The typical operating range is from 100kHz to 2MHz.

4. Peak Current Limit (ILIM):

   • The peak current limit is internally set to 1.8A. This can be externally adjusted if necessary.

5. Reference Voltage (VREF):

   • The internal reference voltage is set to 0.8V, which is used in conjunction with feedback resistors to set the output voltage.

6. Power Good Threshold (VPGOOD):

   • The power good signal activates when the output voltage reaches 90% of its setpoint. The threshold is typically 1.17V.

7. Soft-Start Time (tSS):

   • The soft-start time is fixed at 2.2ms to prevent inrush currents during startup.

8. Enable Input (VENH/VENL):

   • The enable pin should be pulled high above 1.2V to activate the device and below 0.4V to disable it.

9. Quiescent Current (IQ):

   • The quiescent current is typically 3.5mA under no-load conditions.

For detailed design considerations, refer to the full datasheet available from the manufacturer's website.
