Microchip Technology MIC2605YML-TR Boost Converter

The MIC2605YML-TR from Microchip Technology is a high-efficiency, 1.2MHz fixed-frequency, synchronous boost converter that is designed to provide an adjustable output voltage from a single-cell Li-Ion battery. This component is ideal for use in portable electronic devices where extended battery life is essential, and space is at a premium.

Operating from an input voltage range of 2.5V to 10V, the MIC2605YML-TR is capable of delivering an output voltage that can be adjusted up to 34V, making it versatile for powering OLED displays, GPS systems, and other portable devices that require a higher voltage than what the battery can supply. Its high switching frequency allows the use of small, low-profile inductors and ceramic capacitors, reducing the overall footprint of the power supply design on the circuit board.

One of the key features of the MIC2605YML-TR is its synchronous rectification, which greatly improves efficiency compared to traditional boost converters that use diodes. This efficiency, combined with a quiescent current of just 34µA, helps to maximize battery life. Furthermore, the device includes a range of safety features such as under-voltage lockout, thermal shutdown, and current limit protection to ensure reliable operation under various conditions.

The MIC2605YML-TR comes in a compact 10-pin 3x3mm MLF® package, which is suitable for space-constrained applications. The small package size, combined with the minimal number of external components required due to the integrated synchronous rectifier and internal compensation, makes this boost converter an excellent choice for designers looking to minimize the size of their power management solutions.

Overall, the MIC2605YML-TR is an excellent choice for design engineers who need a compact, efficient, and reliable boost converter for their portable applications. Its high efficiency, adjustable output voltage, and integrated safety features make it a robust solution for extending battery life in a wide range of portable electronics.
