AL9910-5S-13

Diodes Incorporated · LED Drivers · SO-8

AL9910-5S-13 from Diodes Incorporated, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in High-voltage input voltage pin, rated up to 500V recommended operating (-0.5 to +520V absolute maximum), powering the internal LDO.
2 CS input Senses LED string and external MOSFET switch current; threshold 250mV nominal (237.5 to 262.5mV for AL9910-5), absolute maximum -0.3 to +0.45V.
3 GND power_in Device ground.
4 GATE output Drives the gate of the external MOSFET switch, swinging up to VDD (7.5V nominal for AL9910-5).
5 PWM_D input Low frequency PWM dimming pin and enable input with internal 200kΩ pulldown to GND; low level 0 to 1V, high level 2.4V to VDD.
6 VDD power_out Internally regulated supply voltage, 7.5V nominal for AL9910-5, able to supply up to 1mA to external circuitry and needing a storage capacitor.
7 LD input Linear dimming input that changes the current-sense comparator threshold and average LED current; 0 to 250mV range.
8 ROSC passive Oscillator control; a resistor to ground sets the PWM frequency, or connected to the external MOSFET gate for constant off-time (PFM) mode.
