MCP1252T-33X50I/MS: Powering Your Designs with High-Efficiency 3.3V Conversion

In the realm of portable and space-constrained electronics, efficient power management is paramount. The MCP1252T-33X50I/MS stands out as a specialized solution, a high-efficiency, fixed 3.3V output charge pump DC/DC converter designed to deliver a stable 50mA output current. This integrated circuit (IC) offers a compelling alternative to traditional inductive switching regulators, particularly in applications where magnetic components are undesirable due to size, cost, or EMI concerns.

The core advantage of this charge pump architecture is its simplicity and magnetic-free operation. By utilizing a network of capacitors to multiply and regulate voltage, the MCP1252 achieves a compact and straightforward design. It operates with an input voltage range from 2.0V to 5.5V, making it exceptionally versatile for systems powered by a single lithium-ion cell (3.0V to 4.2V), two or three alkaline/NiMH cells, or a 5V rail. Its fixed 3.3V output ensures a clean and stable voltage source for low-power microcontrollers, sensors, and other peripheral ICs that are ubiquitous in modern designs.

A key performance metric for any power converter is its efficiency. The MCP1252T-33X50I/MS excels here, boasting high power conversion efficiency across a significant portion of its load range. This efficiency directly translates to extended battery life for portable devices, a critical selling point for consumer and industrial products alike. Furthermore, the device features a low quiescent current, minimizing power drain when the system is in a standby or sleep mode.

The device is offered in the miniature MSOP-8 package, which is crucial for applications where PCB real estate is at a premium. Additional built-in protections, such as integrated short-circuit and over-temperature protection, enhance the robustness of the design, safeguarding both the converter itself and the downstream components from potential damage. Its simple external component requirement—only three small ceramic capacitors—further reduces the total solution size and bill-of-materials (BOM) cost.

ICGOOFind: The MCP1252T-33X50I/MS is an ideal power management solution for designers seeking a simple, reliable, and efficient method to generate a 3.3V rail from a varying input source. Its magnetic-free design, high integration, and protective features make it a superior choice for a wide array of battery-powered and compact applications.
