Product Description
Microchip MCP1642B-50I/MS is a synchronous boost regulator designed for efficient DC-DC voltage step-up applications. This device features a single output channel with an open drain output type, supporting a maximum output voltage of 5.5 V and a minimum output voltage of 1.8 V, with output currents ranging from 175 mA to 800 mA. The device operates with a low input voltage capability starting at 350 mV, enabling power solutions compatible with one to three cell battery sources including alkaline, Li-Ion, NiMH, and others.
The regulator utilizes a fixed-frequency synchronous topology operating up to 1 MHz to achieve typical efficiencies up to 96%. Its internal synchronous rectifier along with integrated compensation and protections reduces the need for external components, simplifying design. Applications are augmented by features such as inrush current limiting, soft-start, over temperature protection, and a low shutdown current of 1 microampere.
Its robust operating temperature span from -40°C to 125°C makes it suitable for industrial, automotive (non-certified), and other demanding environments. Packaged in a standard 8-pin SOP format, it facilitates easy mounting on compact circuit boards.
High-efficiency synchronous step-up DC-DC converter with low voltage start-up. Internal synchronous rectifier and compensation circuitry minimizes external components. Open drain output designed to indicate output voltage status for microcontroller interface.
Supports a broad battery input voltage range suitable for portable and industrial power systems. Comprehensive protection features including thermal shutdown and inrush current limit. Ideal for power management in electronic devices, instrumentation, and industrial control systems.
This 1-channel boost regulator caters to applications requiring reliable and efficient voltage boosting with minimal external component requirements. It is well suited for use in industrial electronics, portable instrumentation, and power supply modules within HVAC, communication devices, and automotive non-certified electronics.
