TC1044SEOA Description

Short technical summary and product information.

The TC1044SEOA from Microchip Technology is a charge pump DC-DC voltage converter designed for efficient voltage conversion. It accepts an input voltage range from 1.5V to 12V and can generate a corresponding negative output voltage.

 

This device is suitable for applications requiring a negative power supply, such as RS-232 interfaces. It operates with a low supply current of 80µA at 5V input and features a switching frequency of 10kHz, which can be boosted to 45kHz for smaller external capacitor requirements.

 

The TC1044SEOA is available in an 8-pin SOIC package, suitable for surface mount applications. It requires only two external capacitors, simplifying circuit design and reducing component count. The operating temperature range is -40°C to 85°C.

 

Key electrical specifications include an output current capability of 20mA and a voltage conversion efficiency of up to 99.9%. The device offers improved ESD protection up to 10kV.
