Microchip Technology's MCP1623T-I/CHY

The MCP1623T-I/CHY is a high-efficiency, compact, synchronous step-up DC-DC converter from Microchip Technology, designed to operate from a 2.0V to 5.5V input voltage range, making it ideal for portable applications powered by single-cell batteries or dual-cell alkaline/NiCd/NiMH batteries. This versatile component is also well-suited for use in products powered by a standard 3.3V or 5V power rails.

One of the standout features of the MCP1623T-I/CHY is its integrated synchronous rectifier, which enhances efficiency, especially in low-voltage applications. This allows for a more efficient transfer of energy, resulting in longer battery life and reduced heat generation. Its high switching frequency, which is up to 2MHz, enables the use of small surface-mount inductors and capacitors, saving valuable board space and reducing overall solution cost.

The device offers a true output disconnect feature that prevents leakage current from the output to the input when the device is disabled, further conserving battery life. Additionally, the MCP1623T-I/CHY has an under-voltage lockout (UVLO) feature that ensures the device operates at the correct input voltage, protecting both the converter and the load from insufficient power conditions.

For design flexibility, the MCP1623T-I/CHY provides an adjustable output voltage option, allowing designers to set the output voltage to a desired level using external resistors. This feature makes the device suitable for a wide variety of applications. Furthermore, its over-temperature protection and over-current protection features ensure reliable operation under various conditions, safeguarding the device and the system it powers.

Encased in a compact SOT-23 package, the MCP1623T-I/CHY is an excellent choice for space-constrained applications, such as handheld devices, wireless sensors, and other portable electronics. By integrating the MCP1623T-I/CHY into their designs, developers can achieve a high-efficiency power solution that minimizes the footprint on their PCBs and supports the creation of smaller, more energy-efficient products.
