ADP3603AR Frequently Asked Questions (FAQ)
-
A good PCB layout is crucial for the ADP3603AR. Ensure a solid ground plane, keep the input and output traces short and separate, and use a common-mode choke to reduce EMI. Refer to the ADP3603AR evaluation board layout as a reference.
-
Choose X5R or X7R ceramic capacitors with a voltage rating of at least 2x the input voltage. For the input capacitor, select a value between 1uF to 10uF, and for the output capacitor, choose a value between 2.2uF to 22uF. Ensure the capacitors are placed close to the IC and have a low ESL.
-
The ADP3603AR can handle input voltages up to 36V, but it's recommended to operate within the specified range of 12V to 24V for optimal performance and reliability.
-
Ensure good thermal design and heat dissipation. Use a heat sink or a thermal pad, and keep the device away from heat sources. Monitor the junction temperature (TJ) and ensure it stays within the specified range of -40°C to 125°C.
-
To prevent damage, ensure the input voltage (VIN) is applied before the enable pin (EN) is asserted. When shutting down, assert the EN pin low before removing the input voltage.
