3 / 35 page PGND/EP Connect to AGND 5 AGND 6 AGND 3 AGND 1 VIN 2 VIN 4 EN 7 FB SS 9 NC 10 VOUT 11 VOUT 8 LMZ13608 www.ti.com SNVS710I – MARCH 2011 – REVISED DECEMBER 2015 5 Pin Configuration and Functions NDY Package 11-Pin Top View Pin Functions PIN TYPE DESCRIPTION NAME NO. AGND 3 Ground Analog Ground — Reference point for all stated voltages. Must be externally connected to EP/PGND. 5 6 EN 4 Analog Enable — Input to the precision enable comparator. Rising threshold is 1.274 V typical. Once the module is enabled, a 20-µA source current is internally activated to accommodate programmable hysteresis. FB 7 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 AGND to set the output voltage. NC 9 — No Connect. This pin must remain floating, do not ground. PGND — Ground 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. SS 8 Analog Soft-Start/Track input — To extend the 1.6-ms 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 Design Steps section. VIN 1 Power Supply input — Nominal operating range is 6 V to 36 V. A small amount of internal capacitance is contained within the package assembly. Additional external input capacitance is required between this 2 pin and PGND. VOUT 10 Power Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and PGND. 11 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) (2) (3) MIN MAX UNIT VIN to PGND –0.3 40 V EN to AGND –0.3 5.5 V SS, FB to AGND –0.3 2.5 V AGND to PGND –0.3 0.3 V Junction temperature 150 °C Storage temperature, Tstg –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
