Instructions for L6599DTR

1. Supply Voltage (VCC):

   • Ensure the supply voltage is within the specified range of 16.5V to 28.0V to avoid damage or improper operation.

2. Switching Frequency (fSW):

   • The internal oscillator sets the switching frequency between 50kHz and 200kHz. Adjust external components if a specific frequency within this range is required.

3. Maximum Duty Cycle (DMAX):

   • The maximum duty cycle is set at 50%. Do not exceed this value to prevent potential instability in the circuit.

4. Current Limit (ILIM):

   • The overcurrent protection threshold ranges from 1.5A to 3.0A. Design your circuit to ensure currents do not consistently reach these limits to maintain reliable operation.

5. Input Voltage UVLO (VUVLO):

   • The under-voltage lockout feature activates when the input voltage drops below 14.5V, ensuring the device shuts down safely until the voltage rises above 16.0V.

6. Propagation Delay (tPD):

   • The typical propagation delay is around 70ns. Consider this delay in timing-sensitive applications.

7. Power Consumption (ICC):

   • The quiescent current consumption is typically 9mA. Factor this into your power budget calculations.
