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