4 / 14 page Pin configuration ST763A series 4/14 2 Pin configuration Figure 2. Pin connections (top view) Table 1. Pin description Pin N° Symbol Name and function 1 SHDN Shutdown control (active low): If connected to GND the IC is in shutdown. Connect to VCC for normal operation (ON MODE). 2 REF Reference output voltage: (1.25V): Bypass to GND with 47nF capacitor. 3SS Soft start: a capacitor between SS and GND provides soft-start and short-circuit protections. 4CC Compensation capacitor input: externally compensates the outer (voltage) feedback loop. Connect to OUT with 330pF capacitor 5OUT Output voltage sense input: provides regulation of feedback sensing. Connect to 3.3V output. 6 GND Ground 7 LX Switch output. Drain of internal P-channel power MOSFET 8VCC Supply voltage input. Bypass to GND with 1 μF ceramic capacitance and large value electrolytic capacitor in parallel. The 1 μF capacitor must be as close as possible to the GND and VCC pins. |
