STMicroelectronics · LED Drivers · QFN-24-EP(5x5)

ALED7707TR from STMicroelectronics, in a QFN-24-EP(5x5). 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 COMP passive Error amplifier output; a simple RC series network between this pin and ground is needed to compensate the boost regulator loop.
2 RILIM passive Output row current limit setting; the row output current is programmed by a resistor connected to SGND.
3 BILIM passive Boost converter current limit setting; the internal MOSFET current limit is programmed by a resistor connected to SGND.
4 FSW input Switching frequency selection via a resistor to SGND, also used as the external synchronization input (see Section 5.1.5).
5 MODE input Current generator fault management selector, allowing LED failures to be detected and managed (see Section 5.3.2).
6 AVCC power_in +5 V analog supply; connect to LDO5 through a simple RC filter.
7 LDO5 power_out +5 V LDO output and power section supply; bypass to SGND with a 1 µF ceramic capacitor.
8 VIN power_in Input voltage; connect to the main supply rail (4.5 V to 36 V input voltage range).
9 SLOPE passive Slope compensation setting; a resistor between the boost converter output and this pin is needed to avoid sub-harmonic instability.
10 SGND power_in Signal ground; supply return for the analog circuitry and the current generators.
11 ROW1 output Row driver output #1 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
12 ROW2 output Row driver output #2 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
13 ROW3 output Row driver output #3 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
14 ROW4 output Row driver output #4 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
15 ROW5 output Row driver output #5 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
16 ROW6 output Row driver output #6 (current generator sink, up to 85 mA adjustable); an unused row can be left floating.
17 PGND power_in Power ground; source of the internal power MOSFET.
18 OVSEL input Overvoltage selection; sets the desired overvoltage threshold through an external divider (see Section 5.1.4).
19 LX output Switching node; drain of the internal power MOSFET.
20 DIM input Dimming input; used to set the brightness externally with a PWM signal.
21 EN input Enable input; when low the device is turned off, and when high or left open the device turns on and a soft-start sequence takes place.
22 FAULT output Open-drain fault signal output that goes low when a fault condition is detected (see Section 5.3.1).
23 SYNC output Synchronization output used for external synchronization of the device.
24 SS passive Soft-start; connect a capacitor to SGND to set the desired soft-start duration.
25 TPAD power_in Thermal pad; electrically connected to SGND and must not be left floating.
