PRODUCTION DATA.
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
EN | 2 | Analog | Active-high enable input for the device. |
Exposed Pad | — | Ground | Exposed pad is used as a thermal connection to remove heat from the device. Connect this pad to the PCB ground plane in order to reduce thermal resistance value. EP must also provide a direct electrical connection to the input and output capacitors ground terminals. Connect EP to pin 4. |
FB | 5 | Analog | Feedback pin. This is the inverting input of the error amplifier used for sensing the output voltage. Keep the copper area of this node small. |
GND | 4 | Ground | Power ground and signal ground. Provide a direct connection to the EP. Place the bottom feedback resistor as close as possible to GND and FB pin. |
SS | 3 | Analog | Soft-start control pin. An internal 2-µA current source charges an external capacitor connected between SS and GND pins to set the output voltage ramp rate during start-up. The SS pin can also be used to configure the tracking feature. |
VIN | 1 | Power | Power supply input. A low-ESR input capacitance should be located as close as possible to the VIN pin and exposed pad (EP). |
VOUT | 6, 7 | Power | The output terminal of the internal inductor. Connect the output filter capacitor between VOUT pin and EP. |
