Pin Functions

PIN NAME PIN NO. TYPE DESCRIPTION
SOIC-D HVSSOP-DGN
CT 4 4 O Reset-pulse delay adjustment. Connecting a capacitor from this pin to GND changes the PG reset delay; see the Reset Delay Timer (CT) section for more details.
EN — 2 I Enable pin. The device enters the standby state when the enable pin becomes lower than the enable threshold.
FB/DNC — 7 I Feedback pin when using external resistor divider or DNC pin when using the device with a fixed output voltage.
GND 5 5 G Ground reference
NC 3 3 — Not-connected pin
PG 6 6 O Power good. This open-drain pin must connect to VOUT via an external resistor. VPG is logic level high when VOUT is above the power-on-reset threshold.
SI 2 I Sense input pin to supervise input voltage. Connect via an external voltage divider to VIN and GND.
SO 7 O Sense output. This open-drain pin must connect to VOUT via an external resistor. VSO is logic level low when VSI falls below the sense-low threshold.
VIN 1 1 P Input power-supply voltage
VOUT 8 8 O Regulated output voltage
