Pinout and pin descriptio | Pin | Name | Type | Function | |---|---|---|---|-| 1 | ISENSE | input | Current sense input. Connect resistor RS from this pin to VIN to define nominal average output current: IOUT_NOM = 0.1/RS. Mean sense threshold voltage is 100mV (typ). |-| 2 | GND | power_in | Ground (0V). |-| 3 | GND | power_in | Ground (0V). |-| 4 | VSET | input | Multi-function On/Off, brightness control, and soft-start pin. Leave floating for normal operation. Drive below 0.2V to disable output (shutdown). DC voltage 0.3V-2.5V provides analog dimming (5%-100% of IOUT_NOM linear range). Accepts PWM signal (open-collector/drain) for 1%-100% dimming at f < 500Hz. A capacitor from VSET to GND sets soft-start time (default 0.1ms; ~1.5ms per 1nF). |-| 5 | LX | output | Switch node - drain of internal 40V NDMOS switch (RON = 0.2Ω typ). Connect to inductor and Schottky freewheeling diode. Current limit 2A typ. |-| 6 | LX | output | Switch node - drain of internal 40V NDMOS switch (RON = 0.2Ω typ). Connect to inductor and Schottky freewheeling diode. Current limit 2A typ. |-| 7 | N/C | unconnected | No Connection. |-| 8 | VIN | power_in | Input voltage supply, 4.5V to 40V (abs max 42V). Decouple to GND with 10µF or higher X7R ceramic capacitor close to the device. |-| EP | EP | passive | Exposed thermal pad. Connect to GND and thermal mass for improved thermal impedance.
