Microchip Technology's TC1220ECH Voltage Converter

The TC1220ECH is a high-performance, charge pump voltage converter produced by Microchip Technology. This device is designed to meet the needs of a wide range of applications requiring efficient voltage level conversion. It stands out for its ability to provide a stable output voltage with a minimal number of external components, making it an ideal solution for space-constrained designs.

The TC1220ECH operates by converting a +2.5V to +5.5V input voltage into a corresponding -2.5V to -5.5V output voltage, effectively doubling the input voltage in a negative configuration. This feature is particularly useful in systems that require a dual supply from a single positive supply source. With its high output current capability of up to 20mA, this voltage converter can easily support various low-power applications.

One of the key advantages of the TC1220ECH is its high efficiency, which can reach up to 99% under certain conditions. This efficiency is made possible by the device's low-power consumption and the use of a high-frequency (45kHz typical) charge-pump oscillator, which reduces the size of the external capacitors needed. As a result, the TC1220ECH is not only powerful but also economical in terms of both energy and space.

The device is available in a compact 6-pin SOT-23A package, making it suitable for portable electronic devices where size is a critical factor. Its thermal shutdown feature ensures protection against overheating, and its low quiescent current makes it an excellent choice for battery-operated equipment.

Whether it's for mobile phones, PDAs, or other handheld devices, the TC1220ECH from Microchip Technology provides designers with a reliable and space-efficient voltage conversion solution. Its ease of integration, coupled with Microchip's reputation for high-quality semiconductor products, makes the TC1220ECH a go-to option for engineers looking to enhance their power management systems.
