The TPS43335-Q1 and TPS43336-Q1 devices are designed to operate from an input voltage up to 40 V. Ensure that the input supply is well regulated. Furthermore, if the supply voltage in the application is likely to reach negative voltage (for example, reverse battery) a forward diode must be placed at the input of the supply. For the VIN pin, a good quality X7R ceramic capacitor is recommended. Capacitance derating for aging, temperature, and DC bias must be taken into account while determining the capacitor value. Connect a local decoupling capacitor close to the Vreg for proper filtering. The PowerPAD™ package, which offers an exposed thermal pad to enhance thermal performance, must be soldered to the copper landing on the PCB for optimal performance.
