MIC4720YML-TR Voltage Regulator by Microchip Technology

The MIC4720YML-TR from Microchip Technology is a high-performance, synchronous step-down (buck) regulator, designed to deliver a continuous output current of up to 2A. This efficient voltage regulator offers an adjustable output voltage range from 0.7V to 5.5V, making it suitable for a wide array of applications, including distributed power systems, portable devices, and networking equipment.

Operating at a switching frequency of 1MHz, the MIC4720YML-TR allows for the use of small surface-mount inductors and capacitors, reducing the overall footprint and component cost on the PCB. This feature, combined with a compact 8-pin 2mm x 2mm MLF® package, makes it an excellent choice for space-constrained applications.

The device integrates a range of protection features to ensure reliable operation under various conditions. These include under-voltage lockout (UVLO), thermal shutdown, and over-current protection (OCP). Additionally, the MIC4720YML-TR boasts a high efficiency of up to 95%, which helps to minimize power loss and heat generation, thereby enhancing system performance and longevity.

The MIC4720YML-TR is capable of operating over a wide input voltage range of 2.7V to 5.5V, which is compatible with standard battery technologies and common bus voltages. Its low dropout operation ensures maximum efficiency even when the input voltage is close to the output voltage. Furthermore, the device features a 100% duty cycle low dropout mode, which allows it to maintain output voltage regulation even when the input voltage drops below the set output voltage.

For design flexibility, the MIC4720YML-TR includes an enable pin that allows the user to turn the regulator on and off, providing a simple means to control power consumption in power-sensitive applications. With its robust design, compact size, and comprehensive feature set, the MIC4720YML-TR voltage regulator is an ideal solution for designers looking to optimize power management in their next project.
