Texas Instruments provides a recommended PCB layout in the application note SLUA271, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The input capacitor selection depends on the input voltage, output voltage, and desired ripple current. TI recommends using a low-ESR capacitor with a value between 10uF to 22uF, and a voltage rating of at least 1.5 times the maximum input voltage. Refer to the application note SLUA271 for more details.
The 8512401EA is rated for operation up to 85°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation. Consult the datasheet and application notes for thermal derating guidelines.
TI recommends using external voltage supervisors, such as the TLV7031 or TLV7041, to implement OVP and UVP. These devices can be connected to the 8512401EA's enable pin to shut down the converter in case of voltage faults.
TI recommends using a low-ESR ceramic or polymer capacitor with a value between 10uF to 47uF, and a voltage rating of at least 1.5 times the maximum output voltage. The output capacitor selection depends on the output voltage, output current, and desired ripple voltage.
