Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply for the internal VCC regulator; bypass with 100-nF capacitor to GND located close to the controller. |
| 2 | SS | bidirectional | Soft-start programming pin accepting capacitor to AGND for extended start-up time or shorted to GND to disable switching. |
| 3 | RT/SYNC | bidirectional | Oscillator frequency programming pin accepting resistor to AGND or external clock synchronization through 100-nF series capacitor. |
| 4 | PWM | input | PWM dimming input; driving below 2.3 V (typ) turns off switching and sets DDRV to ground; duty cycle controls average LED current. |
| 5 | COMP | bidirectional | Transconductance error amplifier output requiring compensation network connected to achieve desired closed-loop response. |
| 6 | IADJ | input | LED current reference input accepting 0 V to 2.25 V for analog dimming; connect to VCC via 100 kΩ resistor to set 2.42 V internal reference. |
| 7 | IMON | output | LED current report pin providing output voltage VIMON = 14 × ILED × RCS; bypass with 1-nF ceramic capacitor to AGND. |
| 8 | AGND | power_in | Analog ground return for internal voltage reference and analog circuit; connect to circuit ground GND to complete return path. |
| 9 | CSN | input | Current sense amplifier negative input (-); connect directly to negative node of LED current sense resistor RCS. |
| 10 | CSP | input | Current sense amplifier positive input (+); connect directly to positive node of LED current sense resistor RCS. |
| 11 | DDRV | output | Series dimming FET gate driver output capable of sinking and sourcing ±500 mA peak current; connect to low-side N-channel MOSFET or level-shifted P-channel MOSFET. |
| 12 | OVP | input | Hysteretic overvoltage protection input with 1.24 V threshold; connect resistor divider from output voltage to set OVP threshold and hysteresis. |
| 13 | PGND | power_in | Power ground connection pin for internal N-channel MOSFET gate drivers; connect to circuit ground GND to complete return path. |
| 14 | IS | input | Switch current sense input; connect to switch current sense resistor RIS in the source of the N-channel MOSFET with 525 mV limit threshold. |
| 15 | GATE | output | N-channel MOSFET gate driver output capable of sourcing/sinking ±500 mA peak current; connect to gate of external switching N-channel MOSFET. |
| 16 | VCC | power_in | VCC bias supply pin providing 7.5 V regulated output; locally decouple to PGND using 2.2-4.7 µF ceramic capacitor located close to controller. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
