Product Description

Microchip MCP1642B-ADJI/MS is a synchronous boost DC-DC converter designed for applications requiring efficient step-up voltage conversion. It delivers a fixed-frequency PWM operation at 1 MHz, providing an output voltage of up to 5.5V and 800 mA output current with typical efficiencies reaching 96%. The device is suited for power management in alkaline, NiCd, NiMH, Li-Ion, and Li-Polymer battery-powered systems.

This surface mount boost converter features a compact MSOP package (3mm x 3mm x 1.1mm) optimized for space-constrained PCB designs. It incorporates an internal synchronous rectifier, compensation, soft-start, inrush current limiting, and thermal shutdown to ensure robustness and low noise operation.

Key technical aspects include a low startup voltage of 0.65V, adjustable output voltage from 1.8V to 5.5V, and a maximum input voltage limit of 5.5V. Its operating temperature range of -40°C to 85°C makes it suitable for diverse industrial, automotive, and communication equipment applications. The shutdown current is less than 1 μA, supporting energy-saving modes.

Typical efficiency as high as 96% reduces energy waste. Max output current can reach 800 mA depending on input voltage conditions. Adjustable output voltage range supports flexible design requirements. Internal over-temperature protection ensures device safety.

Small footprint surface mount MSOP package simplifies integration. Wide temperature operation suits harsh environmental conditions.

This boost converter is ideal for industrial automation, portable instruments, battery-powered devices, and communication systems seeking reliable and efficient voltage step-up solutions.
