FB
The feedback pin provides the control path to control the
output. FB requires a resistor divider network to the
output and GND to set the output voltage.
SW
The switching pin connects directly to one end of the
inductor to VIN and the anode of the Schottky diode to
the output. Due to the high switching speed and high
MIC2619
voltage associated with this pin, the switch node should
be routed away from sensitive nodes.
GND
The ground pin is the ground path for high current PWM
mode. The current loop for the power ground should be
kept as small as possible.
