MIC2287-15YM Product Overview

The MIC2287-15YM is a high-efficiency, 1.2MHz PWM (Pulse Width Modulated) synchronous buck (step-down) regulator from Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. Designed to deliver a fixed output voltage of 1.5V from an input voltage range of 2.5V to 10V, this compact and versatile regulator is an ideal solution for space-constrained applications that require a high power density and efficient power conversion.

Key Features

• High Efficiency: The MIC2287-15YM offers up to 96% efficiency, which minimizes power loss and heat generation, making it suitable for battery-powered devices.
• Adjustable Output Voltage: While providing a fixed 1.5V output, the device allows for output voltage adjustability with external resistors for design flexibility.
• High-Frequency Operation: With a 1.2MHz switching frequency, the MIC2287-15YM allows for the use of small, low-cost inductors and capacitors, reducing the overall solution size.
• Low Quiescent Current: It features a low quiescent current that extends battery life in portable applications.
• Thermal Shutdown: The built-in thermal shutdown feature ensures protection against overheating, enhancing the reliability of the device.
• Under-Voltage Lockout (UVLO): This feature prevents the device from operating at insufficient voltages, which could lead to inefficient performance or damage.

Applications

The MIC2287-15YM is suited for a wide range of applications, including but not limited to:

• Portable devices such as smartphones, tablets, and GPS units
• Wireless and DSL modems
• Digital cameras and audio devices
• Low-voltage, high-density power systems
