Texas Instruments provides a recommended layout and placement guide in the TPS60211 datasheet, which includes guidelines for component placement, PCB routing, and thermal considerations. Additionally, the TI website offers a PCB layout checklist and a thermal design guide for further guidance.
The selection of the output capacitor depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. The capacitor should also be placed as close as possible to the output pin of the TPS60211DGSRG4.
The TPS60211DGSRG4 has an absolute maximum input voltage rating of 6.5V. However, the recommended input voltage range is 2.7V to 5.5V. Operating the device above the recommended input voltage range may affect its performance and reliability.
To ensure stability, TI recommends following the recommended component values and PCB layout guidelines in the datasheet. Additionally, the output capacitor should be selected to meet the minimum capacitance and ESR requirements. The input capacitor should also be selected to meet the minimum capacitance and ESR requirements, and should be placed as close as possible to the input pin of the TPS60211DGSRG4.
The typical startup time for the TPS60211DGSRG4 is around 1ms, but this can vary depending on the input voltage, output voltage, and output current. The startup time can be affected by the input capacitor value, output capacitor value, and the load current.
