A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device can help to dissipate heat efficiently. TI recommends a minimum of 2 oz copper thickness and a thermal pad size of at least 10 mm x 10 mm.
To ensure reliable start-up and shutdown, TI recommends a soft-start circuit with a ramp-up time of at least 1 ms and a shutdown delay of at least 10 ms. Additionally, a 10 nF capacitor on the EN pin can help to filter out noise and ensure clean start-up and shutdown.
TI recommends a 10 uF to 22 uF X5R or X7R ceramic capacitor with a voltage rating of at least 10 V for the input capacitor. This helps to filter out input noise and ensure stable operation.
The output capacitor value and type depend on the specific application requirements. As a general guideline, TI recommends a 10 uF to 47 uF X5R or X7R ceramic capacitor with a voltage rating of at least 2.5 V for most applications. However, for high-current or high-ripple applications, a larger capacitor value or a specialized capacitor type (e.g., OS-CON or polymer) may be required.
The LMZM33606RLXR is rated for operation from -40°C to 125°C ambient temperature. However, TI recommends derating the device for reliable operation above 85°C ambient temperature.
