Pinout and package
PackageTO-PMOD (7), 10.16 mm × 9.85 mm
| Pin | Name | Function | Source |
|---|---|---|---|
| 1 | VIN | - Power Supply input, additional external input capacitance required between this pin and the exposed pad (EP) | |
| 2 | RON | - ON-time resistor, external resistor from VIN to this pin sets the ON-time and frequency, typical values 100k to 700k ohms | |
| 3 | EN | - Enable, input to the precision enable comparator, rising threshold is 1.18 V | |
| 4 | GND | - Ground, reference point for all stated voltages, must be externally connected to EP | |
| 5 | SS | - Soft-Start, internal 8-μA current source charges an external capacitor to produce the soft-start function | |
| 6 | FB | - Feedback, internally connected to the regulation, overvoltage, and short-circuit comparators, regulation reference point is 0.8 V, connect feedback resistor divider to set output voltage | |
| 7 | VOUT | - Output Voltage, output from the internal inductor, connect the output capacitor between this pin and the EP | |
| EP | EP | - Exposed Pad, internally connected to pin 4, used to dissipate heat, must be electrically connected to pin 4 external to the package |
