CN5612 from ShangHai Consonance Elec, in a TO-252-5. 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 | NC | unconnected | No connect. Not internally bonded; leave floating or tie to a non-signal net. |
| 2 | VDD | power_in | Positive supply input and internal circuit power. Operating range 2.7V to 6V; absolute maximum 6.5V. |
| 3 | GND | power_in | Power ground return. The exposed backside tab of the TO-252 should be soldered to the PCB ground copper for maximum thermal performance. |
| 4 | LED | output | LED cathode connection (open-drain current sink). Sinks the regulated constant current (up to 1.2A) programmed by RISET; LED anode connects to VIN. Must be kept below 6V under all conditions. |
| 5 | ISET | input | Constant LED current program pin. Connect a resistor RISET between ISET and VDD; ILED = 910V / RISET (A, Ω). Pulling ISET to VDD (0V across RISET) fully turns off the LED current. |
