Texas Instruments Adjustable DC/DC Inverting Charge Pump 200mA SOT-23-6
Texas Instruments adjustable inverting charge pump, 200mA output, 2.7V to 5.5V input, SOT-23-6 surface-mount package. Rated -40°C to +85°C.
The Texas Instruments Adjustable DC/DC Inverting Charge Pump is a 200mA surface-mount voltage inverter in a compact SOT-23-6 package. It accepts a positive input voltage and converts it to an adjustable negative output, making it a practical choice for generating negative supply rails from a single positive source.
Overview
Operating from an input range of 2.7V to 5.5V, the charge pump is compatible with common low-voltage supplies, including single-cell Li-ion batteries and 3.3V or 5V system rails. It delivers a maximum output current of 200mA, which is suitable for powering analogue circuits, operational amplifiers, sensors, and other components that require a negative bias voltage. The output voltage is adjustable between -2.7V and -5.5V, allowing it to be set to match the requirements of a specific application.
