AO3434A Frequently Asked Questions (FAQ)
-
A thermal pad is recommended under the package to improve thermal performance. A minimum of 2oz copper thickness and a thermal relief pattern are recommended for optimal heat dissipation.
-
Ensure the input voltage is within the recommended range (4.5V to 28V) and the output voltage is set correctly using the FB pin. Also, ensure the input capacitor is properly sized and placed close to the device.
-
The maximum allowable ripple current on the input capacitor is 1A. Exceeding this value may reduce the lifespan of the capacitor or cause it to fail prematurely.
-
No, it's not recommended to use a ceramic capacitor for the output filter. Ceramic capacitors can resonate with the inductor and cause instability. Instead, use a low-ESR electrolytic capacitor or a film capacitor.
-
The inductor value can be calculated using the following formula: L = (Vin * (1 - D)) / (f * ΔI), where Vin is the input voltage, D is the duty cycle, f is the switching frequency, and ΔI is the desired ripple current.
