A good PCB layout for the TPS79601DCQG4 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 TPS79601DCQG4 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 TPS79601DCQG4 can handle a maximum input voltage of 6.5V. Exceeding this voltage may cause damage to the device.
The output voltage of the TPS79601DCQG4 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 typical dropout voltage of the TPS79601DCQG4 is around 300mV at an output current of 1A.
