AL8807MP-13 from Diodes Incorporated, in a MSOP-8-EP. 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 | SET | input | Set nominal output current pin. A sense resistor RS between VIN and SET programs the LED current: IOUTnom = VTH/RS where VTH is typically 100 mV (95-105 mV). SET pin input current is typically 16 µA, max 22 µA (VSET = VIN-0.1). |
| 2 | GND | power_in | Ground pin. Dominant conduction path for junction-to-lead thermal impedance. |
| 3 | GND | power_in | Ground pin (tied internally with pin 2). |
| 4 | CTRL | input | Dimming and On/Off control input. Leave floating for normal operation (VCTRL = VREF = 2.5V, IOUTnom = 0.1/RS). Drive < 0.4V to turn off the output MOSFET. A DC voltage of 0.5V-2.5V linearly scales output current from 20% to 100%. Accepts PWM (low ≤ 0.4V, high > 2.6V, transitions < 1µs) for PWM dimming. Internal pull-up to 2.5V reference through ~50 kΩ. |
| 5 | SW | output | Switch pin (drain of internal high-side MOSFET). Connect the inductor and freewheeling diode here; keep track length short to reduce EMI. RDS(on) ≈ 0.25 Ω (max 0.4 Ω at ISW = 1A). Continuous switch current 1.3A (MSOP-8EP), peak 2.5A. SW voltage rating -0.3 to +40V. |
| 6 | SW | output | Switch pin (tied internally with pin 5). Doubled up for current handling and thermal dissipation. |
| 7 | N/C | unconnected | No connection. Leave floating or tie to a suitable node per PCB layout preference. |
| 8 | VIN | power_in | Input supply pin. Operating range 6V to 36V (absolute max 40V). Must be locally decoupled to GND with a ≥ 2.2 µF X7R ceramic capacitor. Quiescent current typ 350 µA (not switching); typ 1.8 mA at 250 kHz switching with CTRL floating. |
| EP | EP | passive | Exposed pad / thermal tab. Connect to GND and thermal copper for enhanced thermal impedance (θJC ≈ 4.3 °C/W). Should not be used as an electrical ground conduction path. |
