Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output traces short, using a solid ground plane, and minimizing noise coupling. Additionally, ensure the PCB is designed to handle the high currents and voltages involved.
The selection of input and output capacitors depends on the specific application and operating conditions. Generally, choose capacitors with low ESR, high ripple current rating, and a voltage rating that exceeds the maximum input voltage. The datasheet provides guidance on capacitor selection, but it's essential to consult the capacitor manufacturer's datasheet and application notes as well.
The PT6526E is rated for operation up to 85°C ambient temperature, but it's essential to consider the thermal design and heat dissipation in the system. Ensure proper airflow, heat sinking, and thermal management to prevent overheating and ensure reliable operation.
The PT6526E has built-in OVP and UVP features, but they can be adjusted or customized using external components. Consult the datasheet and application notes for guidance on implementing OVP and UVP using resistors, zener diodes, and other components.
The PT6526E is designed to operate from a wide input voltage range (4.5V to 18V), but the optimal performance is typically achieved between 7V and 15V. Operating outside this range may affect efficiency, stability, and reliability.
