Microchip Technology MCP1252T-ADJI/MS Charge Pump DC-DC Converter

The MCP1252T-ADJI/MS from Microchip Technology is a highly efficient, compact charge pump DC-DC converter designed for applications requiring a regulated output voltage from an unregulated input source. This component is part of the MCP1252 series and comes in a small 8-MSOP (Micro Small Outline Package) footprint, making it an ideal choice for space-constrained applications.

With an adjustable output voltage range, the MCP1252T-ADJI/MS provides designers with the flexibility to set the output voltage to a desired level between 1.5V and 5.0V using external resistors. This feature allows the device to be tailored to suit the needs of various applications, including battery-powered devices, handheld equipment, and other portable consumer electronics.

The MCP1252T-ADJI/MS operates with an input voltage range of 1.8V to 5.5V, making it compatible with multiple power sources such as single cell, multi-cell alkaline, NiCd, NiMH, and Li-Ion batteries. Its low quiescent current contributes to the overall power efficiency, which is crucial for battery-operated devices where power conservation is paramount.

Additionally, the device features a low-noise regulated output that is maintained even under varying load conditions and input voltages, ensuring consistent performance and reliability. It also includes thermal shutdown and short-circuit protection, safeguarding the device and connected components from potential damage due to overheating or overcurrent conditions.

The MCP1252T-ADJI/MS also supports a shutdown pin, allowing the device to be turned off, which further reduces power consumption when the device is not in use. This makes it an excellent choice for applications that require extended battery life and infrequent operation.

Overall, the MCP1252T-ADJI/MS charge pump DC-DC converter from Microchip Technology is a versatile and reliable solution for a wide range of applications requiring a regulated voltage source. Its adjustable output, low power consumption, and protective features, packaged in a compact MSOP, make it a valuable component for designers looking to optimize their power management systems.
