Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Switch Collector | output | Internal Darlington switch collector, rated 0 to +40 V with switch current up to 1.5 A. |
| 2 | Switch Emitter | output | Internal Darlington switch emitter, rated −0.6 V to +VCC when the transistor is off. |
| 3 | Timing Capacitor | passive | Timing capacitor (oscillator) node that sets the oscillator frequency, rated −0.2 V to +1.4 V. |
| 4 | GND | power_in | Ground pin for all internal circuits and the reference for all maximum ratings. |
| 5 | Comparator Inverting Input | input | Inverting input of the internal comparator, rated −0.2 V to +VCC. |
| 6 | VCC | power_in | Supply voltage input, rated 0 to +40 V. |
| 7 | Ipk Sense | input | Peak current sense input that monitors the voltage across an external resistor to limit peak current, rated −0.2 V to VCC + 0.2 V with a 200 mV typical current-limit sense voltage. |
| 8 | N.C. | unconnected | Not connected. |
