Instructions for Use:

  1. Supply Voltage (Vcc):

    • Ensure the supply voltage is within the range of 14V to 30V to avoid damage to the device.
  2. Standby Current (Icc):

    • The quiescent current in standby mode is typically 3.5mA, with a maximum of 5mA. This should be considered when designing the power supply.
  3. Output Current Limit (Iout):

    • The maximum output current is limited to 2A. Exceeding this limit can trigger overcurrent protection.
  4. Frequency Range (fsw):

    • The switching frequency can be set between 20kHz and 100kHz. Choose a frequency that balances efficiency and performance for your application.
  5. Dead Time (tdead):

    • The minimum dead time between high-side and low-side switches is 100ns to prevent shoot-through currents.
  6. Overcurrent Protection (Iocp):

    • The overcurrent protection threshold is set to 1.8A to 2.2A. If the output current exceeds this level, the device will shut down to protect itself.
  7. Thermal Shutdown (Tsd):

    • The device will initiate thermal shutdown at approximately 170°C to prevent damage from overheating.
  8. Operating Temperature Range (Topr):

    • The ambient operating temperature range is from -40°C to 150°C. Ensure the device operates within this range to maintain reliability.
  9. Storage Temperature Range (Tstg):

    • The device can be stored at temperatures ranging from -65°C to 150°C without damage.
  10. Layout Considerations:

    • Use short and wide traces for high-frequency signals and power paths to minimize inductance and parasitic effects.
    • Place decoupling capacitors close to the power pins to ensure stable operation.
  11. Heat Dissipation:

    • Ensure adequate heat dissipation by using a heatsink or thermal pad if necessary, especially under high load conditions.
  12. Protection Circuits:

    • Implement additional protection circuits such as input filters and clamping diodes to protect against voltage spikes and transients.
