A small amount of internal capacitance is contained within the package assembly. Additional external input capacitance is required between this pin and PGND. Enable — Input to the precision enable comparator. Rising threshold is 1.274V typical. Once the module is enabled, a 20 uA source current is internally activated to accommodate programmable hysteresis. Feedback — Internally connected to the regulation, over-voltage, and short-circuit comparators. The regulation reference point is 0.8V at this input pin. Connect the feedback resistor divider between the output and AGND to set the output voltage. Soft-Start/Track input — To extend the 1.6 mSec internal soft-start connect an external soft start capacitor. For tracking connect to an external resistive divider connected to a higher priority supply rail. See applications section. No Connect. This pin must remain floating, do not ground. 3, 5, 6 AGND Analog Ground — Reference point for all stated voltages. Must be externally connected to EP/PGND. 4 7 EN FB 8 9 10, 11 EP SS NC VOUT Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and PGND. PGND Exposed Pad / Power Ground Electrical path for the power circuits within the module. — NOT Internally connected to AGND / pin 5. Used to dissipate heat from the package during operation. Must be electrically connected to pin 5 external to the package. 3 www.national.com LMZ13610 Absolute Maximum Ratings (Note 3) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.

Minimum and Maximum limits are guaranteed through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only.
