ABLIC recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure stable output voltage during startup, ABLIC recommends adding a 1uF to 10uF capacitor at the output pin to filter out any noise or oscillations.
Although not explicitly stated in the datasheet, ABLIC recommends keeping the input voltage ripple within 1% of the nominal input voltage to ensure stable operation.
While the S-8425AAAFT-TB-U is rated for operation up to 125°C, ABLIC recommends derating the output current and power dissipation to ensure reliable operation in high-temperature environments.
To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
