AGND 5 Ground Analog Ground — Reference point for all stated voltages. Must be externally connected to EP/PGND. 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. 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. SH 9 Analog Share pin. Connect this to the share pin of other LMZ23608 modules to share the load between the devices. One device must be configured as the master by connecting the FB normally. All other devices must be configured as slaves by leaving their respective FB pins floating. Leave this pin floating if not used, do not ground. See Design Steps section. 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. SYNC 3 Analog Sync Input — Apply a CMOS logic level square wave whose frequency is between 350 kHz and 600 kHz to synchronize the PWM operating frequency to an external frequency source. When not using synchronization this pin must be tied to ground. The module free running PWM frequency is 350 kHz. VOUT 10 Power Output Voltage — Output from the internal inductor. Connect the output capacitor between this pin and PGND. 11 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 2 this pin and PGND.
