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.
