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 — Power 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 pin and PGND.
2
VOUT 10 Power Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and PGND.
