Texas Instruments provides a recommended layout and placement guide in the TPS60242DGKT datasheet, which includes guidelines for component placement, routing, and thermal considerations. Additionally, the TI website provides a layout guide document (SLUU323) that provides more detailed information on layout and placement best practices.
The selection of the output capacitor depends on the specific application requirements, such as output voltage, output current, and ripple voltage. Texas Instruments recommends using a low-ESR ceramic capacitor with a value between 1uF to 10uF. The datasheet provides a detailed explanation of the output capacitor selection process, and TI also provides a capacitor selection tool on their website.
The TPS60242DGKT has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum input voltage can damage the device.
To ensure stability, it is essential to follow the recommended layout and placement guidelines, use a suitable output capacitor, and ensure that the input voltage is within the recommended operating range. Additionally, the datasheet provides a detailed explanation of the stability criteria and how to calculate the required output capacitor value to ensure stability.
The power dissipation of the TPS60242DGKT depends on the input voltage, output voltage, and output current. The datasheet provides a formula to calculate the power dissipation, which is Pd = (Vin - Vout) x Iout + (Vin x Iq), where Iq is the quiescent current. The maximum power dissipation rating is 1.5W.
