STMicroelectronics provides a recommended PCB layout in the application note AN5096, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. A general guideline is to use a low-ESR capacitor with a value between 10uF to 22uF. Refer to the application note AN5096 for more detailed guidance.
Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the internal components.
The TSH72CD does not have built-in OVP. However, you can implement OVP using an external voltage monitor IC, such as the STM6627, which can detect overvoltage conditions and shut down the TSH72CD to prevent damage.
The typical startup time for the TSH72CD is around 10ms to 15ms, depending on the input voltage, output voltage, and load conditions. This can be critical in applications where fast startup is required.
