Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | UVLO | input | Undervoltage lockout input. Use a resistor divider from VIN to this pin to set the UVLO threshold (V_UVLOTH typ 1.229 V). |
| 2 | EN | input | Enable pin. EN high = enable, EN low = disable. Logic high 1.8 V min, logic low 0.8 V max; internal pull-down ~1.6 MΩ. |
| 3 | PWM1 | input | PWM dimming input for LED string 1. Frequency range 90 Hz to 22 kHz; duty cycle sets string brightness independently. |
| 4 | PWM2 | input | PWM dimming input for LED string 2. Frequency range 90 Hz to 22 kHz. |
| 5 | PWM3 | input | PWM dimming input for LED string 3. Frequency range 90 Hz to 22 kHz. |
| 6 | PWM4 | input | PWM dimming input for LED string 4. Frequency range 90 Hz to 22 kHz. |
| 7 | PWM5 | input | PWM dimming input for LED string 5. Frequency range 90 Hz to 22 kHz. |
| 8 | PWM6 | input | PWM dimming input for LED string 6. Frequency range 90 Hz to 22 kHz. |
| 9 | FBP | input | LED cross-short protection threshold program pin. Use a resistor to GND to set the threshold (I_FBP = 0.25 × I_SET at V_FBP = 1 V). |
| 10 | ISET | input | IFB current programming pin. Resistor to GND sets the full-brightness (100% dimming) IFB pin current level. V_ISET typ 1.229 V; K_ISET = I_FB/I_SET ≈ 3992. |
| 11 | IFBV | input | Minimum feedback voltage setting for LED strings. V_IFBV range 0.3 V to 1.0 V; sets the IFB regulation voltage floor. |
| 12 | IFB1 | input | Regulated current sink input for LED string 1. Connects to the cathode of the LED string; sinks up to ~130 mA typical (400 mA pulsed). |
| 13 | IFB2 | input | Regulated current sink input for LED string 2. Connects to the cathode of the LED string. |
| 14 | IFB3 | input | Regulated current sink input for LED string 3. Connects to the cathode of the LED string. |
| 15 | IFB4 | input | Regulated current sink input for LED string 4. Connects to the cathode of the LED string. |
| 16 | IFB5 | input | Regulated current sink input for LED string 5. Connects to the cathode of the LED string. |
| 17 | IFB6 | input | Regulated current sink input for LED string 6. Connects to the cathode of the LED string. |
| 18 | AGND | power_in | Analog ground reference for internal circuitry. |
| 19 | OVP | input | Overvoltage protection detection input. Resistor divider from boost output to this pin programs the OVP threshold (V_OVPTH typ 3.02 V). |
| 20 | COMP | output | Loop compensation output for the boost converter. Connect an RC network from this pin to AGND for loop stability. |
| 21 | REF | output | Internal reference voltage output for the boost controller (0 to 3.1 V range). Capacitor to GND adjusts the soft-start time. In master/slave configurations connect the master's REF to the slave's COMP. |
| 22 | PGND | power_in | External MOSFET current-sense ground input (power ground return for the sense resistor). |
| 23 | ISNS | input | External MOSFET current-sense positive input. Overcurrent detection threshold V_ISNS(OC) typ 400 mV. |
| 24 | GDRV | output | External N-channel MOSFET gate driver output. Sourcing 200 mA / sinking 400 mA typical; absolute max −0.3 V to 7 V (−2 V to 9 V transient <10 ns). |
| 25 | VDD | power_out | Internal LDO regulator output for IC internal power supply (V_DD typ 6.0 V, 5.7 V min, 6.3 V max at 0-15 mA). Connect a 1.0 µF ceramic capacitor from this pin to GND. |
| 26 | FSW | input | Switching frequency setting pin. Resistor to GND sets f_SW between 100 kHz and 800 kHz. Driving above 3.5 V or below 0.5 V disables the internal clock and configures the device as a slave. |
| 27 | FAULT | output | Fault indicator, open-drain output. Goes high impedance when a fault condition is present; sinks 1-2 mA at low output; absolute max −0.3 V to VIN. |
| 28 | VIN | power_in | Power supply input pin. Operating range 8 V to 30 V; absolute max −0.3 V to 33 V. UVLO threshold ~6.5 V (falling) with 300 mV hysteresis. |
| 29 | PowerPAD | power_in | Exposed thermal pad on the underside of the HTSSOP-28 package. Connect to ground plane for heat dissipation. |
