Microchip Technology's MCP1256/7/8/9EV Product Overview

The MCP1256/7/8/9EV series from Microchip Technology represents a family of highly integrated charge pump DC-DC converters that are designed to efficiently manage power within space-constrained applications. These devices are a perfect fit for products requiring a compact power solution, as they are capable of converting input voltages ranging from 2.0V to 5.5V to regulated output voltages of 3.3V or 5V, which is essential for consistent device performance.

The series includes the following models:

• MCP1256 - Adjustable output voltage
• MCP1257 - Fixed 3.3V output
• MCP1258 - Fixed 5V output
• MCP1259 - Adjustable output with a low noise LDO

Each of these models is offered in a compact package, making them suitable for portable devices such as handheld instruments, medical devices, and wireless products. The MCP1256/7/8/9EV devices feature a low quiescent current and high efficiency, which is crucial for battery-powered applications where energy conservation is paramount.

One of the standout features of this series is the inclusion of a low-power shutdown mode, which further extends battery life by reducing the power consumption to a negligible level when the device is not in active use. Additionally, the series is designed to operate over a broad temperature range, ensuring reliability and performance in various environmental conditions.

For design flexibility, these charge pumps offer a selectable 2x or 1.5x mode, allowing designers to optimize the converter's performance for specific application requirements. The MCP1259 model includes a low-dropout regulator (LDO) for applications demanding low noise power supply rails.

Microchip Technology provides comprehensive support for the MCP1256/7/8/9EV series, including evaluation boards and detailed datasheets to assist designers in rapid prototyping and integration into their projects. The robust design and versatility make the MCP1256/7/8/9EV series an excellent choice for a wide range of power management applications.
