## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PWMI | input | Device enable and PWM dimming control input; turn-on threshold 1.34 V to 1.65 V, dimming frequency 0.1 to 20 kHz, shutdown when held low more than 10 ms. |
| 2 | FSW | input | Switching frequency setting via a resistor to SGND (100 kHz to 1 MHz) and synchronization clock input; tied high (e.g. to LDO3) sets 600 kHz. |
| 3 | XFAULT | output | Open-drain fault indicator output, pulled low by the device in case of a faulty condition. |
| 4 | LDO3 | power_out | 3.3 V linear regulator output and device supply; connect a 1 µF (typ.) MLCC bypass to SGND close to the chip. |
| 5 | SGND | power_in | Signal ground, return for analog circuitry; all setting components must refer to this pin. |
| 6 | COMP | passive | Boost controller loop compensation; a simple RC series must be connected between this pin and SGND. |
| 7 | ADIM | input | Analog dimming control input; output current is linearly controlled by the voltage applied (0.3 V to 1.2 V). |
| 8 | OVFB | input | Output overvoltage protection feedback input; connect to the central tap of a resistor divider at the output (1.2 V typ. threshold). |
| 9 | CSNS | input | Boost controller power switch current sensing input; connect to the source of the external power MOSFET (OCP threshold 360 mV typ.). |
| 10 | PWMO | output | PWM dimming control output in phase with PWMI, for direct drive of a dimming N-channel MOSFET. |
| 11 | PGND | power_in | Power ground, return for the VDR linear regulator and gate drivers and reference for power MOSFET current sensing. |
| 12 | GATE | output | Power switch gate driver output; connect to the gate of the power MOSFET through a small value resistor. |
| 13 | VDR | power_out | 5 V linear regulator output and gate driver supply; connect a 1 µF (typ.) MLCC bypass to PGND close to the chip. |
| 14 | VIN | power_in | Supply voltage input, 5.5 V to 36 V; connect a 1 µF (typ.) MLCC between this pin and PGND close to the chip. |
| 15 | VFBN | input | Output current differential sensing input, negative terminal; connect to the hot (load side) terminal of the high-side sensing resistor. |
| 16 | VFBP | input | Output current differential sensing input, positive terminal; connect to the quiet (output capacitor side) terminal of the high-side sensing resistor. |
| 17 | TPAD | power_in | Thermal pad; connect to a suitable ground plane area for heat dissipation, electrically connected to PGND and SGND. |
