Power Supply Recommendations

The power supply to the TPS63710 needs to have a current rating according to the input supply voltage, output voltage and output current of the TPS63710. The peak current requirement on the input depends on the duty cycle, as CCP is charged during the off-time. Worst case is for the maximum duty cycle of 70% when the OFF-time is at its shortest value of 30%. The peak current on the input can be up to 5 times of the average output current. A proper input capacitor needs to be placed directly at the VIN and GND pins to supply the peak current demand of the converter. Slew rates faster than 1 V/µs for a VIN step of less than 1 V and 0.1 V/µs for a VIN step over the full input voltage range up to 14 V should be avoided, as this leads to a large inrush current through the CCP capacitor and HSD.

When the input supply of TPS63710 is shorted while the device is enabled, the charge stored on the CCP capacitor is transferred to the output. This may cause an output voltage undershoot. It is recommended to disable the TPS63710 by setting the EN pin to low while the supply voltage is within the recommended input voltage range. This ensures a proper shutdown.
