Product Description
Microchip MCP1623T-I/CHY is a compact and highly efficient 5-channel synchronous step-up DC-DC boost regulator designed to provide power solutions for PIC Microcontrollers in one-, two-, and three-cell battery powered applications. It achieves an adjustable output voltage up to 5.5 V with a switching frequency of 630 kHz, housed in a space-saving SOT-23 6-pin surface mount package with dimensions of 3.1 mm length, 1.8 mm width, and 1.3 mm height.
The boost converter features a low start-up voltage of 0.65 V, enabling operation even under low input voltage conditions, and maintains high efficiency up to 96% through integrated synchronous rectification and internal compensation. It operates with a quiescent current of only 220 μA to conserve battery life and includes a load disconnect mode that reduces input current to less than 1 μA when disabled, making it highly suitable for low power applications.
Protective features include over-temperature shutdown, inrush current limiting, and internal soft-start, ensuring reliable operation in demanding industrial and electronic applications. The device complies with RoHS standards and supports a wide operating temperature range from -40°C to 125°C.
This regulator is ideal for applications in automotive electronics, industrial instruments, portable electronics, and telecommunications where compact size, low power consumption, and reliable voltage regulation are critical.
