Functional Pin Description Pin No. TSSOP-14 (Exposed Pad) WDFN-10L 3x3 SOP-8 (Exposed Pad) Pin Name Pin Function 1 -- -- VS Output Voltage Sense Input. 2 2 2 FB Feedback Voltage Input. It is used to regulate the output of the converter to a set value via an external resistive voltage divider. The feedback threshold voltage is 0.765V typically. 3 3 3 VREG5 Internal Regulator Output. Connect a 1 μF capacitor to GND to stabilize output voltage. 4 4 4 SS Soft-Start Time Setting. Connect an external capacitor between this pin and GND to set the soft- start time. 5 -- -- GND Analog Ground. 6 5 -- PGOOD Open Drain Power Good Indicator Output. 7 1 1 EN Enable Control Input. A logic-high enables the converter; a logic-low forces the IC into shutdown mode reducing the supply current to less than 10 μA. 8, 9, 15 (Exposed pad) 11 (Exposed pad) 5, 9 (Exposed Pad) PGND Power Ground. The exposed pad must be soldered to a large PCB and connected to PGND for maximum power dissipation. 10, 11 6, 7 6 SW Switch Node. Connect this pin to an external L-C filter. 12 8 7 BOOT Bootstrap Supply for High Side Gate Driver. Connect a 0.1 μF capacitor between the BOOT and SW pin. 13 9, 10 8 VIN Power Input. The input voltage range is from 4.5V to 18V. Must bypass with a suitably large ( ≥10μF x 2) ceramic capacitor. 14 -- -- VCC Supply Voltage Input for Internal Linear Regulator to the Control Circuitry. |
