GUID-20220422-SS0I-5CJM-KGF1-Q6SDGCWVBPBT-low.svg Figure 5-1 6-Pin SOT563 DRL Package (Top View)
Table 5-1 Pin Functions
Pin Type(1) Description
Name NO.
VIN 1 P Input voltage supply pin. Connect the input decoupling capacitors between VIN and GND.
SW 2 P Switch node pin. Connect the output inductor to this pin.
GND 3 G GND pin for the controller circuit and the internal circuitry.
PG 4 A Open-drain power-good indicator.
EN 5 A Enable control input. Driving EN high enables the converter.
FB 6 A Converter feedback input. Connect to output voltage with a feedback resistor divider.
