Power-up Procedure
RT1719GQW is a sink only Type-C port controller. The main function is to request Vbus (Fixed Power) for the system. RT1719GQW requests the matched and maximum power Source PDO according to the settings at Table_SEL, PSEL2, and PSEL1. Table_SEL, PSEL2, and PSEL1 can be configured by adjusting JP964, JP955, and JP961 respectively. The following two tables show the Sink PDO for 128 configurations.

EVB Schematic Diagram
1. The capacitance values of the input and output capacitors will influence the input and output voltage ripple.
2. MLCC capacitors have degrading capacitance at DC bias voltage, and especially smaller size MLCC capacitors will have much lower capacitance.
Evaluation Board Layout
Figure 1 to Figure 4 are RT1719GQW Evaluation Board layout. This board size is 70mm x 50mm and is constructed on four-layer PCB, outer layers with 2 oz. Cu and inner layers with 1 oz. Cu.
