LED2000DR from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Regulator switching pin. Connects to the external inductor; the internal high-side and low-side synchronous power MOSFETs alternately switch this node between VINSW and PGND at the 850 kHz oscillator frequency to deliver regulated LED current. |
| 2 | PGND | power_in | Power ground. Return path for the internal low-side synchronous rectifier MOSFET; carries the high pulsed switching current and should be tied to the input capacitor ground with a short, wide trace. |
| 3 | VINA | power_in | Analog circuitry power supply connection. Feeds the internal reference, bandgap, oscillator, error amplifier, and control logic. Operating range 3.0 V to 18 V; absolute max -0.3 V to 20 V. Typically bypassed with a small local ceramic filter capacitor (e.g. 100 nF) to signal ground. |
| 4 | DIM | input | Dimming/enable control input. Logic low (< 0.4 V) prevents switching activity, logic high (> 1.2 V) enables it. Apply a square wave for PWM LED brightness dimming. Tie to VINA if unused. Input bias current ~2 uA typ.; absolute max -0.3 V to VINA. |
| 5 | FB | input | Feedback input (inverting input of the internal transconductance error amplifier). Connect a sense resistor RS = 100 mV / ILED between this pin and ground to program the regulated LED current. Internal reference 100 mV typ.; input bias current 600 nA max; absolute max -0.3 V to 2.5 V, ±1 mA. |
| 6 | AGND | power_in | Analog circuitry ground connection. Return for the low-noise analog reference, error amplifier, and control blocks. Should be tied to signal-ground island and joined to PGND at a single quiet point (typically under the output capacitor). |
| 7 | GND | power_in | Ground pin present only on the SO8-BW package. Datasheet instruction is to connect this pin directly to AGND; provides additional ground bonding for the analog side of the die. |
| 8 | VINSW | power_in | Power input voltage supplying the internal high-side power MOSFET drain. Operating range 3.0 V to 18 V; absolute max -0.3 V to 20 V. Requires a low-ESR input decoupling capacitor placed as close as possible to this pin and PGND. |
