1 Introduction

Figure 1-1 and Figure 1-2 shows the typical application schematics of the two devices. The VIN pin for TPS92630-Q1 and the SUPPLY pin for TPS92638-Q1 are power supply input pins. The voltage of the supply pins are expressed as V(supply) hereinafter. The supported supply voltage range of TPS92630/8-Q1 is 5 V - 40 V.
