A2, B2 3, 4 GND_SW G A connection to the source terminal of the integrated power MOSFET. A3 5 SDA I/O I2C data input/output pin A4 6 SCL I I2C clock input pin B3 9 PWM I PWM dimming input. Supply a 75-Hz to 25-kHz PWM signal to control dimming. This pin must be connected to GND if unused. B4 7 EN / VDDIO P Dual-purpose pin serving both as a chip enable and as a power supply reference for PWM, SDA, and SCL inputs. Drive this pin with a logic gate capable of sourcing a minimum of 1 mA. C1 22 VDD P Device power supply pin. Provide 2.7-V to 20-V supply to this pin. This pin is an input of the internal LDO regulator. The output of the internal LDO is what powers the device. C2 20 VBOOST A Boost converter output pin. The internal feedback (FB) and overvoltage protection (OVP) circuitry monitors the voltage on this pin. Connect the converter output capacitor bank close to this pin. C3 21 FSET A A connection for setting the boost frequency and PWM output dimming frequency by using an external resistor. Connect a resistor, RFSET, between this pin and the ground reference (see Table 5). This pin may be left floating if PWM_FSET_EN = 0 AND BOOST_FSET_EN = 0 (see Table 10). C4 14 LED3 A LED driver - current sink terminal. If unused, it may be left floating. D1 19 VLDO P Internal LDO output pin. Connect a capacitor, CVLDO, between this pin and the ground reference. D2 23 ISET A A connection for the LED current set resistor. Connect a resistor, RISET, between this pin and the ground reference. This pin may be left floating if ISET_EN = 0 (see Table 10). D3 10, 11, 15, 24, DAP GND I Ground pin. D4 13 LED2 A LED driver - current sink pin. If unused, it may be left floating. E1 18 LED6 A LED driver - current sink pin. If unused, it may be left floating. E2 17 LED5 A LED driver - current sink pin. If unused, it may be left floating. E3 16 LED4 A LED driver - current sink pin. If unused, it may be left floating. E4 12 LED1 A LED driver - current sink pin. If unused, it may be left floating. — 8 NC — No Connect pin. |
