The boost converter regulates the minimum voltage between LED1, LED2 to VHR. A2 ASEL Input ASEL is a logic input which selects between two I2C address options. This pin is read on power up (VIN going above 1.8 V, and HWEN going above a logic high voltage). GND = address 0x36, logic high = address 0x37. A3 GND Input Ground B1 LED2 Input Input pin to current sink 2. The boost converter regulates the minimum voltage between LED1, LED2 to VHR. B2 SDA I/O Data I/O for I2C-Compatible Interface. B3 SW Output Drain connection for internal low side NFET, and anode connection for external Schottky diode. C1 NC Input Unused pin. Connect externally to GND. C2 SCL Input Clock input for I2C-compatible interface. C3 OUT Input OUT serves as the sense point for overvoltage protection. Connect OUT to the positive pin of the output capacitor. D1 PWM Input Logic level input for PWM current control. D2 HWEN Input Hardware enable input. Drive HWEN high to bring the device out of shutdown and allow I2C writes or PWM control. D3 IN Input Input voltage connection. Bypass IN to GND with a minimum 2.2-µF ceramic capacitor. |
