AO3460 Frequently Asked Questions (FAQ)
-
The maximum junction temperature of the AO3460 is 150°C. However, it's recommended to keep the junction temperature below 125°C for reliable operation.
-
To ensure proper biasing, connect the enable pin (EN) to a logic high (VCC) and the input voltage (VIN) should be within the recommended range of 4.5V to 28V. Additionally, ensure the output voltage (VOUT) is within the specified range for the desired output current.
-
For optimal PCB layout, place the input capacitors (CIN) close to the VIN pin, and the output capacitors (COUT) close to the VOUT pin. Keep the high-current paths short and use a solid ground plane to reduce EMI. Also, ensure good thermal conduction by placing thermal vias under the IC and using a heat sink if necessary.
-
The output voltage ripple of the AO3460 can be calculated using the following formula: ΔVOUT = (IOUT * ESL) / (COUT * fSW), where ESL is the equivalent series inductance of the output capacitor, IOUT is the output current, COUT is the output capacitance, and fSW is the switching frequency.
-
The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric capacitor. The recommended value is 10uF to 22uF, depending on the input voltage and output current requirements.
