Table 5-1 Pin Functions
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 k to 700 k Ω. Recommended frequency for a 4-A load is 300 kHz.
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 exposed pad (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.

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications.
(3) For soldering specifications, see the application note Absolute Maximum Ratings for Soldering (SNOA549)
