STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, frequency, and ripple current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and a capacitance value between 10uF to 100uF. Consult the application note AN4979 for more detailed guidance.
The maximum allowed voltage drop across the THBT200S is 1.5V. Exceeding this voltage drop may lead to reduced efficiency, increased heat generation, or even damage to the device.
The THBT200S is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. Consult the datasheet and application notes for guidance on thermal management and derating.
To ensure EMC, follow the guidelines in the application note AN4979, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consult the IEC 61000-4-x standards for electromagnetic compatibility testing.
