Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PWM/EN | input | PWM dimming signal input and IC enable/disable control; pulling low for more than 20ms disables the IC and enters shutdown mode |
| 2 | VLDO | output | Internal pre-regulator output of 3.0V to 3.5V for internal circuit supply; connect a 1µF ceramic bypass capacitor |
| 3 | ISET | input | Current setting pin; connect a resistor to program the full-scale LED current per equation IFBx_full = 1.04V × 1024 / RISET |
| 4 | COMP | passive | Boost loop compensation pin; connect a 0.47µF to 1µF ceramic capacitor for loop stability and soft-start control |
| 5 | IFB4 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 6 | IFB5 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 7 | IFB6 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 8 | GND | power_in | Analog ground connection |
| 9 | IFB1 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 10 | IFB2 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 11 | IFB3 | output | Regulated current sink output with maximum 35mA output current per channel; ±2.3% maximum accuracy over -40°C to +85°C |
| 12 | OVP | input | Over-voltage protection monitoring pin; connect through external resistor divider to sense boost output voltage up to 38V |
| 13 | PGND | power_in | Power ground connection for high-current switching path return |
| 14 | SW | output | Drain of the internal 2A/40V power MOSFET; switching node with maximum voltage rating of 40V |
| 15 | VIN | power_in | Supply input pin accepting 2.7V to 6.5V; provides power to the IC with maximum quiescent current of 3mA |
| 16 | MODE/FAULT | output | Multi-function pin for dimming mode programming via external resistor and active driver (via internal current sink) for external P-channel isolation MOSFET gate control |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
