4 / 16 page 2 Pin Configuration STCF01 4/16 2 Pin Configuration Table 1. Pin Description Figure 2. Pin Connnections (Top View ) PlN N° SYMBOL NOTE 1PWRGND This is the application power signal reference. Connect the input and output capacitors to this pin. 2OVP This pin senses step-up output voltage, which provides overvoltage protection in the event that the output voltage exceeds the OVP threshold 3 VI This pin supplies the input voltage for the step-up stage as well as the supply voltage for the overall device. 4HC This pin sets the high level current for the white LEDs with a resistor that is connected between this pin and VI. 5LC This pin sets the low level current for the white LEDs with a resistor that is connected between this pin and VI. 6 SGLGND This pin is the logic signal reference for the IC. 7FB This pin senses the current flowing through the white LEDs and uses this feedback to provide current regulation. 8 SEL This pin is used to select the signal level of the white LEDs; a low level signal sets the low level LED current, while the high level signal sets the high level LED current. 9SHDN This pin enables or disables the Shutdown mode. A high level signal enables device Shutdown mode, where most of the device internal logic is turned OFF. If this pin is held to GND, the output current flows through the LEDs continuously (Torch mode). 10 SW This is the switch node pin, which is connected to the internal N-channel MOSFET drain. |
