The MIC2130-1YTSE-TR is a high-efficiency, high-voltage, monolithic DC to DC switching controller from the PMIC (power management integrated circuit) family. It is designed for use in computing, communications and consumer electronics equipment ranging from personal computers, laptops, printers, and other consumer electronics to networking products and wireless systems. The MIC2130-1YTSE-TR is a voltage regulator, a DC to DC switching controller, with an internal current limit. It is an excellent choice for both 3V and 5V systems that require high conversion efficiency, low cost, and low noise.

The MIC2130-1YTSE-TR integrates all necessary functions for implementing a synchronous buck (step-down) converter. It contains a highly efficient 1A/2A integrated switch, a full range design (up to 19V high-side, down to 0.5V low-side), a fast synchronous rectifier, a wide operating frequency range (2MHz-8MHz), a wide input voltage range (up to 19V) and current-mode control using a constant frequency with adjustable slope compensation. It has a very compact 4-by-2mm QFN package.

The MIC2130-1YTSE-TR has several important features that make it an ideal choice for an efficient DC to DC switching regulator. It uses synchronous rectification and has an internal 1A integrated switch with low RDS and a VDS range up to 19V. It also has a wide operating frequency range from 2MHz to 8MHz, ensuring high efficiency and low EMI. It has a wide input voltage range up to 19V, allowing for easy design of power systems with multiple power sources. Furthermore, it uses current-mode control and a constant frequency with adjustable slope compensation for improved system stability, as well as an external compensation pin for further customization.

The MIC2130-1YTSE-TR is designed with an internal current limit ratio of 1A+2A. The maximum output current is 2A, where the output voltage can be regulated within 0.5V of the desired value. In order to secure maximum efficiency, the switch-current sense amplifier can be tuned to maximize the drain-to-source voltage and minimize power dissipation. For safety, the controller has adjustable overcurrent protection, overtemperature protection, and a hiccup mode.

The MIC2130-1YTSE-TR also provides some further features and benefits. It has an internal thermal shutdown circuitry that provides protection from overheating, and it includes an enable pin for a simple system shutdown procedure. Additionally, it comes in a thermally enhanced QFN package that reduces power dissipation, improving switch efficiency. Finally, it has low EMI and reduced switching noise, making it ideal for use in noise-sensitive applications.

Overall, the MIC2130-1YTSE-TR is an excellent choice for high performance and cost-effective DC to DC switching applications. With its wide input voltage range and constant frequency with adjustable slope compensation, it offers excellent efficiency and robustness, while its adjustable current limit ratio, enable pin, integrated thermal shutdown, and QFN package further enhance its performance and make it an ideal choice for digital power systems.
