Microchip MIC22200YML-TR: 2A High-Efficiency Miniature Step-Down Regulator with Integrated Switches
In the relentless pursuit of miniaturization and power efficiency in modern electronics, the Microchip MIC22200YML-TR stands out as a premier solution for power management. This device is a synchronous step-down (buck) DC-DC regulator engineered to deliver a robust 2A continuous output current from a compact, space-optimized package. Its advanced design integrates critical power components, making it an indispensable component for a wide array of power-sensitive applications.
Key Features and Advantages
The core strength of the MIC22200 lies in its highly integrated design. The regulator incorporates both high-side and low-side MOSFET power switches synchronously within the same package. This integration drastically reduces the external bill of materials (BOM), saving valuable PCB real estate and simplifying the design-in process. Designers no longer need to source and lay out discrete power switches, leading to a more reliable and compact end product.
Despite its miniature footprint, the MIC22200 does not compromise on performance. It operates at a 2MHz fixed switching frequency, which is high enough to allow the use of tiny, low-profile inductors and capacitors. This high frequency, combined with a proprietary switching architecture, enables the converter to achieve exceptional power conversion efficiency, often exceeding 95% under optimal conditions. This high efficiency is paramount for battery-powered devices, as it minimizes energy loss in the form of heat and maximizes battery run-time.
The input voltage range of 2.7V to 5.5V makes it perfectly suited for systems powered by a single-cell Li-ion battery or a standard 3.3V/5V rail. It provides a adjustable output voltage from 0.6V to the input voltage (VIN), allowing it to power the latest low-voltage microprocessors, FPGAs, ASICs, and other core logic.
Furthermore, the MIC22200 is equipped with a full suite of protection features to ensure system robustness. These include undervoltage lockout (UVLO), over-current protection (OCP), and thermal shutdown. These safeguards protect both the regulator itself and the sensitive load it powers from potential damage due to fault conditions.
Target Applications
The combination of high current, small size, and high efficiency makes the MIC22200YML-TR ideal for a multitude of portable and space-constrained applications, including:
Portable Medical Devices and health monitors

RF Modules, IoT Sensors, and Wearable Technology
Solid-State Drives (SSDs) and data storage systems
Portable Consumer Electronics such as smartphones and tablets
Networked Appliances and distributed point-of-load (POL) systems
ICGOODFIND Summary
The Microchip MIC22200YML-TR is a highly integrated, high-efficiency synchronous buck regulator that delivers 2A of output current. Its miniature package, which includes integrated power switches, makes it a superior choice for designers aiming to achieve maximum power density and extended battery life in modern electronic products.
