Renesas provides a recommended PCB layout guide in their application note AN1965, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure optimal performance.
Renesas provides a component selection guide in their datasheet, which includes recommendations for input and output capacitors, inductors, and resistors. Additionally, the application note AN1965 provides more detailed guidance on component selection and layout considerations.
The ISL91108IINZ-T is rated for operation from -40°C to +125°C ambient temperature range, but the maximum junction temperature (TJ) should not exceed +150°C. It's essential to ensure proper thermal design and heat sinking to maintain a safe operating temperature.
The ISL91108IINZ-T has a built-in overcurrent protection feature that can be enabled by connecting the OC pin to a resistor and capacitor network. The application note AN1965 provides a detailed example of how to implement overcurrent protection and calculate the required component values.
Renesas recommends a specific startup sequence to ensure proper operation of the ISL91108IINZ-T. The sequence involves applying the input voltage, followed by the enable signal, and then the output voltage. The datasheet provides more detailed information on the recommended startup sequence.
