Instructions for RTD2523

1. Power Supply Connection:

   • Connect the input voltage (V_IN) within the specified range of 2.7V to 5.5V.
   • Ensure stable power supply to avoid voltage spikes.

2. Output Configuration:

   • Set up the output circuit to handle a maximum continuous current of 3.0A.
   • Use appropriate PCB trace widths to accommodate high currents and minimize resistance.

3. Thermal Management:

   • The device can operate between -40°C and 85°C. Ensure adequate heat dissipation if operating near the upper temperature limit.
   • Consider adding a heatsink or using a thermal pad under the package for better heat transfer.

4. Switching Frequency:

   • The internal switching frequency is set to 600kHz, which helps in reducing the size of external components like inductors and capacitors.

5. Efficiency Optimization:

   • For optimal efficiency, operate the device close to its typical efficiency point (around 90%).

6. Shutdown Mode:

   • To enter shutdown mode, apply a low signal to the shutdown pin. The quiescent current in this mode will be around 0.1μA.

7. Package Handling:

   • The RTD2523 comes in a DFN package. Handle with care to avoid damage to the leads and ensure proper soldering during assembly.

8. Capacitor Selection:

   • Choose input and output capacitors that can handle the ripple current and provide stable operation over the temperature range.

Note: Always refer to the manufacturer's datasheet for detailed specifications and application notes specific to your design requirements.
