SW 1 O Output switch. Connect to the inductor and catch diode. Signal and power ground pin. Place the bottom resistor of the feedback network as close as GND 2 G possible to this pin. FB 3 I Feedback pin. Connect to external resistor divider to set output voltage. Enable control input. Logic high enables operation. Do not allow this pin to float or be greater EN 4 I than VIN + 0.3 V. VIN 5 I/P Input supply voltage. (1) I: Input Pin, O: Output Pin, P: Power Pin, G: Ground Pin Pin Functions (6-Pin WSON) PIN I/O(1) DESCRIPTION NAME NO. FB 1 I Feedback pin. Connect to external resistor divider to set output voltage. Signal and power ground pin. Place the bottom resistor of the feedback network as close as GND 2 G possible to this pin. SW 3 O Output switch. Connect to the inductor and catch diode. VIND 4 I/P Power Input supply. VINA 5 I/P Control circuitry supply voltage. Connect VINA to VIND on PC board. Enable control input. Logic high enables operation. Do not allow this pin to float or be greater EN 6 I than VINA + 0.3V. Die Attach Connect to system ground for low thermal impedance, but it cannot be used as a primary – – Pad GND connection.
