PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | VIN | Power | Supply input — Additional external input capacitance is required between this pin and the exposed pad (EP). |
2 | RON | Analog | ON-time resistor — An external resistor from VIN to this pin sets the ON-time and frequency of the application. Typical values range from 100 kΩ to 700 kΩ. |
3 | EN | Analog | Enable — Input to the precision enable comparator. Rising threshold is 1.18 V. |
4 | GND | Ground | Ground — Reference point for all stated voltages. Must be externally connected to EP. |
5 | SS | Analog | Soft-Start — An internal 8 µA current source charges an external capacitor to produce the soft-start function. |
6 | FB | Analog | Feedback — Internally connected to the regulation, overvoltage, and short-circuit comparators. The regulation reference point is 0.8 V at this input pin. Connect the feedback resistor divider between the output and ground to set the output voltage. |
7 | VOUT | Power | Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and the EP. |
— | EP | Ground | Exposed Pad — Internally connected to pin 4. Used to dissipate heat from the package during operation. Must be electrically connected to pin 4 external to the package. |
