GENERAL DESCRIPTION

The SGM3209 is a charge pump voltage converter

which is used to generate a negative supply from a

positive input. The 3V to 18V input voltage can be

converted into a corresponding -3V to -18V output

supply. The SGM3209 is also capable of delivering up

to 100mA of output current. The switching frequency is

resistor programmable from 120kHz to 1.25MHz. The

device also has the advantage of using a combination

of few external components to eliminate the inductors

and their associated cost, size and EMI.

The SGM3209 enters into shutdown status by external

enable control signal to reduce system power

dissipation. The device is used for design requirements

with higher output current and/or lower input/output

voltage drop.

The SGM3209 is available in Green TDFN-2×2-8L and

SOIC-8 packages. It operates over an ambient

temperature range of -40℃ to +85℃.
