Introducing the TC1121EPA from Microchip Technology

The TC1121EPA is a high-performance, versatile charge pump voltage converter manufactured by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions. This component is designed to provide a reliable and efficient voltage conversion solution for a wide range of electronic applications.

The TC1121EPA operates by converting a +2.5V to +5.5V input voltage into a corresponding negative voltage output, making it an ideal choice for systems that require a dual power supply from a single power source. Its charge pump technology allows for the creation of a negative voltage without the need for inductors, simplifying the design and reducing the overall component count and board space.

This voltage converter features a high switching frequency of up to 45 kHz, which allows for the use of small external capacitors, further minimizing the footprint and cost of the overall power supply design. Additionally, the TC1121EPA offers a low quiescent current, making it suitable for battery-operated devices where power efficiency is critical.

With its thermal shutdown protection and short-circuit current limiting, the TC1121EPA ensures safe operation under various conditions. The device is also characterized by its low output ripple and noise, which is essential for sensitive analog circuits and precision applications.

The TC1121EPA is available in a compact 8-pin PDIP package, making it easy to integrate into a variety of designs. Its robustness and reliability make it an excellent choice for portable electronics, data acquisition systems, telecommunications, and other applications requiring a high-quality negative voltage supply.

Microchip Technology's commitment to quality means that the TC1121EPA is a product you can trust for your voltage conversion needs. Whether you are designing a new system or upgrading an existing one, the TC1121EPA offers the performance and features necessary to achieve a stable and efficient power supply configuration.
