Instructions for LMR23630ADDAR

1. Input Capacitor Selection:

   • Use a ceramic capacitor with X7R dielectric and low ESR.
   • Recommended value: 1 μF to 10 μF.

2. Output Capacitor Selection:

   • Choose a capacitor with low ESR to minimize output ripple.
   • Recommended value: 10 μF to 47 μF ceramic or equivalent.

3. Inductor Selection:

   • Select an inductor based on the desired output current and ripple current.
   • Typical range: 1 μH to 4.7 μH.

4. Feedback Resistor Network:

   • Set the output voltage using the feedback resistor network (R1 and R2).
   • Formula: ( V_ = V_ times (1 + frac) ).

5. PCB Layout Considerations:

   • Place input and output capacitors close to the IC.
   • Keep the ground plane solid and wide to reduce noise.
   • Ensure thermal considerations are met by providing adequate copper area for heat dissipation.

6. Thermal Protection:

   • The device includes over-temperature protection that shuts down the converter if the junction temperature exceeds 160°C.

7. Enable Pin:

   • The enable pin can be used to turn the device on/off.
   • Apply a logic high (≥1.23V) to enable the device; apply a logic low (≤0.8V) to disable it.

8. Short-Circuit Protection:

   • The device provides automatic recovery from short-circuit conditions at the output.

Ensure all components are rated for the maximum expected voltages and currents in your application. Always refer to the latest datasheet for detailed specifications and guidelines.
