Microchip Technology MCP1624T-I/MC Product Overview

The MCP1624T-I/MC is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC converter from Microchip Technology, a leading provider of microcontroller, mixed-signal, analog, and Flash-IP solutions. This device is specifically designed to operate from a single-cell alkaline, NiCd, NiMH, or Li-Ion battery source, making it an ideal choice for portable, battery-powered applications where extended battery life is essential.

With its input voltage range of 0.35V (start-up) to 5.5V, the MCP1624T-I/MC can continue to operate down to 0.65V after start-up, ensuring that the device can effectively utilize the full capacity of the battery. The output voltage is selectable via external resistors and can be set up to 5.5V, which provides a great deal of flexibility for powering various loads.

The MCP1624T-I/MC employs a pulse-width modulation (PWM) control scheme that provides a fixed switching frequency of 500 kHz, allowing for the use of small, surface-mount inductors and capacitors to minimize the overall solution footprint. Additionally, the device incorporates a low-resistance N-Channel MOSFET and a synchronous P-Channel MOSFET to improve efficiency and reduce power losses.

One of the key features of this step-up converter is its low quiescent current of just 19 µA, which significantly reduces the power drain when the device is in standby mode. This is particularly beneficial for battery-powered applications where energy conservation is critical. Furthermore, the MCP1624T-I/MC includes an under-voltage lockout (UVLO), over-temperature protection, and an automatic shut-down feature to safeguard the device and the connected load under abnormal operating conditions.

The MCP1624T-I/MC is available in a compact 6-pin SOT-23 package, which is well-suited for space-constrained applications. Its robust design and efficiency make it an excellent choice for a wide range of products, including wireless sensors, handheld devices, GPS receivers, and many other portable electronics that require a reliable power conversion solution.

For designers and engineers looking for a power-efficient voltage boost solution, the MCP1624T-I/MC from Microchip Technology offers the performance, reliability, and flexibility needed to develop cutting-edge portable applications.
