Microchip Technology, Inc. Synchronous Boost Regulator, Dfn-8; Topology Microchip MCP1640D-I/MC

The MCP1640/B/C/D is a synchronous boost regulator designed for low-voltage applications, capable of starting up from an input voltage as low as 0.65V. It features a typical efficiency of up to 96% and can handle output currents of up to 350mA depending on the input voltage and output configuration. The output voltage is adjustable within a range of 2.0V to 5.5V, making it suitable for various battery-powered devices, including single-cell Li-Ion and multi-cell alkaline applications. This regulator incorporates automatic PFM/PWM operation, with a low quiescent current of 19µA in PFM mode, ensuring minimal power consumption during standby. It also includes features such as inrush current limiting, internal soft start, and selectable shutdown states, providing either true load disconnect or input/output bypass options. The MCP1640 is available in an 8-lead DFN package, which is compact and suitable for space-constrained designs. Overall, this product is ideal for engineers looking for a reliable and efficient boost converter for portable electronic applications.
