Maximum ratings

Stressing the device above the rating listed in Table 2: Absolute maximum ratings may

cause permanent damage to the device. These are stress ratings only and operation of the

device at these or any other conditions above those indicated in the operating sections of

this specification is not implied. Exposure to absolute maximum rating conditions may affect

device reliability.

PGND

Power GND

Switching node

VIN

DC input voltage

VBIAS

Typically connected to the regulated output voltage. An external voltage reference can be used to

supply part of the analog circuitry to increase the efficiency at light load. Connect to GND if not

used.

E. p.

Exposed pad must be connected to SGND
