onsemi · LED Drivers · SOIC-8

NCL30076AADR2G from onsemi, in a SOIC-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 BIAS power_out This pin is the 3.3 V LDO output that biases the internal digital circuit, with a typical 3.30 V (3.23 to 3.37 V) and a pin voltage range of -0.3 to 5.5 V.
2 CSZCD input This pin senses the switch current and the inductor current zero-cross time, with a pin voltage range of -0.3 to 5.5 V and an over-current threshold of 1.0 V typical (0.9 to 1.1 V).
3 SG power_in Signal ground is routed close to the control pin circuits such as CSZCD, DIM and FB and serves as their reference.
4 FB output This pin is the feedback output of the feedback OTA, with a pin voltage range of -0.3 to 5.5 V and a minimum clamping voltage of 0.5 V typical (0.4 to 0.6 V).
5 DIM input This pin receives the dimming signal, with a pin voltage range of -0.3 to 5.5 V; the standby enabling and disabling thresholds are 75 mV and 100 mV typical.
6 VDD power_in This pin supplies the IC operating current, with a pin voltage range of -0.3 to 30 V, a turn-on threshold of 10.0 V typical and a turn-off threshold of 8.0 V typical, and an over-voltage protection threshold of 23 V typical.
7 DRV output This pin drives the external switch, with a pin voltage range of -0.3 to 30 V, a high level of 12 V typical at VDD = 15 V, and a low level of 0.2 V maximum.
8 PG power_in Power ground is routed close to the capacitors at the BIAS and VDD pins and serves as the power return.
