Pinout and package
Figure 2. Top View 7-Lead PFM
| Pin | Name | Function | Source |
|---|---|---|---|
| 1 | VIN | - Supply input, nominal operating range is 6V to 42V | |
| 2 | RON | - On Time Resistor, external resistor sets the on-time | |
| 3 | EN | - Enable, input to precision enable comparator, rising threshold 1.18V | |
| 4 | GND | - Ground, reference point for all stated voltages, must be externally connected to EP | |
| 5 | SS | - Soft-Start, internal 8μA current source charges external capacitor | |
| 6 | FB | - Feedback, internally connected to regulation, over-voltage, and short-circuit comparators, reference point 0.8V | |
| 7 | VOUT | - Output Voltage, output from the internal inductor | |
| EP | EP | - Exposed Pad, internally connected to pin 4, used to dissipate heat |
