MCP1642B-50I/MS

Detailed Description:

The MCP1642B-50I/MS by Microchip is a compact, high-efficiency, fixed-frequency, synchronous step-up DC-DC converter designed for battery-powered and low-power applications. Housed in an 8-pin MSOP package, it supports input voltages from 0.35V to 5.5V, making it particularly suitable for devices powered by single-cell batteries. This converter is capable of handling output voltages up to 5.0V, making it versatile for a variety of low-power electronics, including portable medical devices, wireless sensors, and handheld instruments. The MCP1642B-50I/MS features a true output disconnect which isolates the load from the battery when switched off, as well as an automatic bypass mode which enhances efficiency when the input voltage is close to the output voltage. With its high switching frequency, it enables the use of small, low-cost inductors and ceramic capacitors, reducing overall solution size and cost. Additionally, its quiescent current is extremely low, enhancing battery life in portable applications. The MCP1642B-50I/MS embodies Microchip’s commitment to providing innovative power management solutions that meet stringent power and space requirements.
