Description

STOD2540 is dedicated to passive matrix OLED

(PMOLED) displays for portable handsets and

provides the pre-charge and biasing voltage of

the column matrix driver as shown in figure 3. The

current capability of STOD2540 allows feeding a

1", 1.3" or 1.5" color PMOLED. STOD2540 is a

boost converter that operates from 3.0 V to 5.5 V

and can provide an output voltage as high as 25

V. The output current capability is maximum 40

mA up to 25 V output voltage. The regulation is

performed by a resistor divider network (figure 3)

that detects the output voltage.

In this state-of-the-art boost converter, a DC

current path exists between the battery source

and the load. In order to reduce the consumption

in shutdown mode, a high-side load isolation

switch is necessary to cut this DC current path in

standby mode. The load disconnect switch (LDS)

act as an isolation switch in shutdown mode.
