Microchip Technology's MIC2287CYD5-TR Step-Down Converter

The MIC2287CYD5-TR is a high-efficiency, 1.2MHz pulse-width modulated (PWM) step-down (buck) converter from Microchip Technology. This compact and powerful integrated circuit is designed to provide a reliable voltage conversion solution for space-constrained applications. It operates over a wide input voltage range from 2.5V to 10V, making it suitable for a variety of power sources, including single-cell lithium-ion batteries, multi-cell alkaline batteries, or regulated 5V and 3.3V power rails.

One of the key features of the MIC2287CYD5-TR is its internal 2A switch, which allows it to deliver up to 2A of output current to the load. This makes it an excellent choice for powering portable devices, wireless equipment, and other low-power electronics. The device's high switching frequency of 1.2MHz enables the use of small external components, thereby reducing the overall footprint and cost of the power supply design.

The MIC2287CYD5-TR also boasts excellent efficiency, which helps extend battery life in portable applications. Its high level of integration includes features such as internal compensation, a fixed-frequency PWM control scheme, and a thermal shutdown mechanism for added protection. Additionally, the converter offers a 'HyperLight Load' mode, which provides very high efficiency at light loads and improves battery life in standby and low-power modes.

For design flexibility, the MIC2287CYD5-TR supports adjustable output voltage, allowing designers to set the output voltage to a desired value using external resistors. The device is available in a small 8-pin 2mm x 2mm MLF® package, which is ideal for applications with limited PCB space.

Microchip Technology's commitment to quality ensures that the MIC2287CYD5-TR meets the stringent requirements of modern electronic devices. Whether you're designing a new product or looking to improve the efficiency of an existing one, the MIC2287CYD5-TR is a reliable and cost-effective choice for your power conversion needs.
