Product Description
Microchip MCP1624T-I/CHY is a 5-channel step-up boost regulator designed for compact and highly efficient power supply applications requiring stable output voltages up to 5.5 V and output currents of up to 50 mA.
This regulator operates with a fixed frequency of 630 kHz and features an adjustable output voltage range between 2.0 V and 5.5 V, which can be set using an external resistor divider.
The device integrates an internal synchronous rectifier and built-in compensation and protection circuitry to minimize external components and improve efficiency, achieving up to 96% typical efficiency. It supports low quiescent current operation of 20 μA and low shutdown current below 1 μA, making it ideal for battery-powered and energy-sensitive applications.
The compact SOT-23 package (6-pin) with dimensions of 3.1 mm length, 1.8 mm width, and 1.3 mm height, facilitates easy surface mounting in small form factor designs. Its operating temperature range of -40°C to 125°C covers a broad spectrum of industrial and commercial environments.
This regulator's low start-up voltage of 0.65 V (typical) at 3.3 V output voltage under a 1 mA load and low operating input voltage of 0.35 V ensure reliable startup from low battery voltages. The built-in inrush current limiting and internal soft-start features contribute to stable power delivery without overshoot.
Common uses include supplying power to PIC microcontrollers in one, two, or three-cell battery applications, automotive electronics, and other embedded systems requiring compact, efficient voltage regulation.
Adjustable output voltage range of 2.0 V to 5.5 V for flexible power designs. Low quiescent current operation (20 μA typical) conserves battery life. High efficiency up to 96% optimizes energy use and thermal management.
Reliable operation over a wide temperature range (-40°C to 125°C) for industrial applications. Compact surface-mount SOT-23 6-pin packaging facilitates PCB space-saving. Built-in synchronous rectifier enhances conversion efficiency.
Soft-start and inrush current limiting protect circuit stability at startup. RoHS compliant and produced in Thailand to meet environmental and quality standards.
