IC CHRG PUMP INVERTER 100MA 8SOIC


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSwitched-capacitor charge pump voltage converter that generates negative voltage from positive supply. Provides inverted output up to -100mA with minimal external components. Commonly used for biasing and negative rail generation in analog circuits, LCD drivers, and portable instrumentation requiring dual-rail supplies.
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
