D1, D0 (Pin 1, 10): Control Inputs. D0 and D1 determine

the set point voltage of the FB pin (see Table 1).

FB (Pin 2): FB is the Feedback Input for the Regulation

Control Loop.

impedance 1

µF X5R or X7R ceramic capacitor is required

with a 1

µF to 4.7µF low impedance ceramic capacitor.

PI FU CTIO S

GND (Pin 5): Ground for the Charge Pump and Control

Circuitry. This pin should be connected directly to a low

impedance ground plane.

µF X5R or X7R ceramic capacitor

PGND (Pin 11, Exposed Pad DFN Only): Power Ground

for the Charge Pump. This pin must be connected directly

to a low impedance ground plane.
