Pin Descriptions
Pin
Name
Description
1
VIN
Supply input — Nominal operating range is 6V to 42V . A small amount of internal capacitance is contained within the
package assembly. Additional external input capacitance is required between this pin and exposed pad.
2
RON
On Time Resistor — An external resistor from V
IN to this pin sets the on-time of the application. Typical values range
from 25k to 124k ohms.
3
EN
Enable — Input to the precision enable comparator. Rising threshold is 1.18V nominal; 90 mV hysteresis nominal.
Maximum recommended input level is 6.5V.
4
GND
Ground — Reference point for all stated voltages. Must be externally connected to EP.
5
SS
Soft-Start — An internal 8 A current source charges an external capacitor to produce the soft-start function. This node
is discharged at 200 A during disable, over-current, thermal shutdown and internal UVLO conditions.
6
FB
Feedback — Internally connected to the regulation, over-voltage, and short-circuit comparators. The regulation
reference point is 0.8V at this input pin. Connected the feedback resistor divider between the output and ground to set
the output voltage.
7
VOUT Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and exposed pad.
EP
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.
