Texas Instruments Adjustable DC/DC Inverting Charge Pump, 200mA, SOT-23-6

The Texas Instruments Adjustable DC/DC Inverting Charge Pump is a high-performance, surface-mount voltage inverter designed for efficient power management in space-constrained electronic designs. This integrated circuit accepts a positive input voltage and inverts it to provide a negative output, all within a compact SOT-23-6 package, making it an ideal solution for generating negative supply rails from a single positive source.

Offering a wide input voltage range from 2.7V to 5.5V, this charge pump provides flexible compatibility with common low-voltage power supplies, including single-cell Li-ion batteries or 3.3V/5V system rails. It delivers a maximum output current of 200mA, sufficient for powering analogue circuits, operational amplifiers, sensors, and other components requiring a negative bias voltage. The output voltage is fully adjustable, allowing you to set it anywhere between -2.7V and -5.5V to precisely match your application's requirements.

Constructed for reliability, the device operates across an extensive industrial temperature range from -40°C to +85°C, ensuring stable performance in demanding environments. Its surface-mount technology (SMT) design facilitates automated assembly and helps minimise the overall footprint on your printed circuit board (PCB).
