A good PCB layout for the TPS79633DCQG4 involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure the stability of the TPS79633DCQG4 output voltage, it's recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the device. Additionally, the output voltage can be stabilized by adding a small ceramic capacitor (e.g. 100nF) in parallel with the output capacitor.
The TPS79633DCQG4 can handle a maximum input voltage of 6.5V. Exceeding this voltage may cause damage to the device.
The output voltage of the TPS79633DCQG4 can be calculated using the following formula: Vout = (R1 / R2) x Vref, where R1 and R2 are the resistors used to set the output voltage, and Vref is the internal reference voltage (1.2V).
The TPS79633DCQG4 can deliver a maximum output current of 3A. Exceeding this current may cause the device to overheat or shut down.
