Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply pin for the controller, rated VDD-to-GND -0.3 to 24 V, with the chip turning on at VDDON 11.5 to 13.5 V and shutting off under-voltage at VDDOFF 5.3 to 6.7 V. |
| 2 | GND | power_in | Ground reference pin for the controller, against which the VDD rating of -0.3 to 24 V is specified. |
| 3 | VFB | input | Voltage feedback input that samples the auxiliary-winding divider for constant-voltage regulation, rated -0.3 to 7 V, with an overvoltage threshold VOVP of 2.95 V and a short-circuit threshold VSCP of 1 V. |
| 4 | CS | input | Current-sense input for cycle-by-cycle peak current limiting, rated -0.3 to 7 V, with a maximum constant-current reference VOCPMAX of 0.475 to 0.52 V and a 400 ns blanking time TLEB. |
| 5 | D | passive | Drain of the internal power MOSFET, rated for a BVDSS of 650 V minimum at VGS=0 V and ID=250 µA, with RDSON of 2.1 Ω at VGS=10 V and ID=1 A. |
| 6 | D | passive | Drain of the internal power MOSFET, rated for a BVDSS of 650 V minimum at VGS=0 V and ID=250 µA, with RDSON of 2.1 Ω at VGS=10 V and ID=1 A. |
| 7 | D | passive | Drain of the internal power MOSFET, rated for a BVDSS of 650 V minimum at VGS=0 V and ID=250 µA, with RDSON of 2.1 Ω at VGS=10 V and ID=1 A. |
| 8 | D | passive | Drain of the internal power MOSFET, rated for a BVDSS of 650 V minimum at VGS=0 V and ID=250 µA, with RDSON of 2.1 Ω at VGS=10 V and ID=1 A. |
