Pin Configuration and Functions

Figure 5-1 SIL 8-Pin µSiL Package(SIL0008C Top View)
Table 5-1 Pin Functions
PIN I/O DESCRIPTION
NAME NO.
EN 1 I Enable pin. Pull High to enable the device. Pull Low to disable the device. This pin has an internal pulldown resistor of typically 400 kΩ when the device is disabled.
VIN 2 PWR Input pin
GND 3 Ground pin
VOUT 4, 5 PWR Output pin
FB 6 I Feedback reference pin. An external resistor divider connected to this pin programs the output voltage.
PG 7 O Power-good open-drain output pin. A pullup resistor can be connected to any voltage less than 6 V. Leave this pin open if it is not used.
SS/TR 8 I Soft start-up and voltage tracking pin. An external capacitor connected to this pin sets the internal reference voltage rising time.
Exposed Thermal Pad The exposed thermal pad must be connected to the GND pin. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
