Description |
1 | NC | Not Connected |
2 | GND | Ground |
3 | SS_INH | A logic signal (Active low) disables the device(Sleep mode operation). A capacitor connected between this pin and ground determines the soft start time. When this pin is grounded disables the device. |
4 | OSC | An external resistor connected between the unregulated input voltage and this pin and a capacitor connected from this pin to ground fix the switching frequency. |
5 | OUT | Stepdown regulator output. |
6 | OUT | Stepdown regulator output. |
7 | NC | Not Connected |
8 | NC | Not Connected |
9 | NC | Not Connected |
10 | NC | Not Connected |
11 | VCC | Unregulated DC input voltage |
12 | BOOT | A capacitor connected between this pin and output allows to drive the internal DMOS transistor. |
13 | COMP | E/A output to be used for frequency compensation. |
14 | FB | Connecting output directly to this pin results in output voltage of 3.3v. An external voltage divider is require for higher output voltages. |
15 | NC | Not Connected |
16 | NC | Not Connected |
