The MCP1640T-I/CHY is an integrated circuit (IC) component manufactured by Microchip Technology. It is a synchronous step-up DC-DC converter specifically designed for portable and battery-powered applications. With a small form factor and low power consumption, the MCP1640T-I/CHY offers several key features that make it suitable for various electronic devices.
One of the main features of the MCP1640T-I/CHY is its ability to boost input voltages from as low as 0.65V to output voltages ranging from 1.8V to 5.5V. This wide input voltage range enables the IC to function efficiently with different power sources, including single-cell, dual-cell, and alkaline or lithium-ion batteries.
The MCP1640T-I/CHY supports a maximum output current of 250mA, making it ideal for low-power applications such as wearable devices, portable medical devices, and wireless sensors. It offers a high conversion efficiency of up to 96% at full load, minimizing power loss and prolonging battery life.
To ensure stable and reliable performance, the MCP1640T-I/CHY includes a variety of protection features. It incorporates overcurrent protection (OCP) to safeguard against excessive currents, preventing damage to the circuit or connected devices. It also includes thermal shutdown protection (TSD), which activates when the IC's internal temperature exceeds a safe limit, preventing overheating and potential damage
