CN5501 from ShangHai Consonance Elec, in a SOP-8-EP. 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 | EQ | bidirectional | LED current equalizing pin; connect to the EQ pin of other CN5501 devices when multiple CN5501 drive multiple LED strings in parallel to equalize LED current. |
| 2 | EN | input | High-voltage enable pin; drive EN high to enable the output, with VIH of 3.1 V minimum, VIL of 0.6 V maximum, and a 36 V absolute maximum rating. |
| 3 | GND | power_in | Ground terminal and negative terminal of the input supply. |
| 4 | CS | input | LED current sense pin; the resistor between CS and GND sets the LED current as ILED = 0.153 ÷ (RCS + 0.03) A, with RCS in ohms. |
| 5 | LED | output | Current sink pin connected to the drain of the on-chip power MOSFET; the LED string(s) connect between LED and VIN, with a 36 V absolute maximum rating on this pin. |
| 6 | VIN | power_in | Positive input supply terminal powering the internal circuit; operating range is 4 V to 32 V with a 36 V absolute maximum rating. |
| 7 | VCC | power_out | +5 V regulator output (5 V typical) with 3 mA output capability; connect a 2.2 µF to 10 µF compensation capacitor from VCC to GND. |
| 8 | NC | unconnected | No connection. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
