Modern electronic devices which consume increasingly small amounts of power require an Analogue Mixed Signal Integrated Circuit (AMIC) designed system to maintain the desired functionality or precision. The MIC38C43-1YM belongs to the family of MIC38C40-1YM boards and specifically designed for energy efficient applications. It is part of Pericom Semiconductor\'s family of high performance power management analogue products.

The MIC38C43-1YM DC-DC switching controllers are specifically designed for medium-to-high frequency switching supplies with high power efficiency and precise output voltage regulation. This MIC38C43-1YM family of devices combines digital and analogue functions that enable the devices to generate precise digital control loops and to maintain the desired output voltage using open loop or closed loop methods. The MIC38C43-1YM provides complete control functions and offer multiple operating modes to meet the needs of a wide range of applications.

The MIC38C43-1YM mainly used in applications such as portable consumer electronics and communications equipment, as well as in industrial equipment and instrumentation. It is designed to provide precise output voltage regulation across a wide range of input voltages, currents and output loads. A wide range of operating modes including single, dual and multi-output on the same board is supported by the MIC38C43-1YM controller. The MIC38C43-1YM provides a high efficiency power management solution for medium-to-high frequency DC-DC switching supplies, along with guaranteed no-load operation in multiple operating modes and low shutdown current for increased power conservation.

The MIC38C43-1YM circuit has two main components. The first component is the feedback control loop controller which provides the necessary precision digital feedback and control signals to the second component; the PWM. This is the main power switch for the output voltage, and is responsible for providing the voltage regulation for the output. The MIC38C43-1YM supports both open loop and closed loop control and uses a single control loop to ensure both voltage and current regulation of the output.

The MIC38C43-1YM also has a wide range of features which make it suitable for a wide range of applications. It supports both synchronous and asynchronous PWM operation, allowing the user to choose the most suitable mode for their application. The device has a low quiescent current of 2.5mA, allowing it to be used in low power applications. It also supports both positive and negative linear mode and burst mode operations, allowing the designer to optimize the system to reduce power consumption and minimize the heat generated, further increasing the efficiency. Additionally, the MIC38C43-1YM has a wide range of operating modes and supports multiple load configurations, allowing it to be used in a variety of systems.

The MIC38C43-1YM provides a high efficiency, low-cost power management solution, with simple control and robust design. As a result, it is ideal for use in medium-to-high frequency DC-DC switching supplies and provides enhanced performance, longer system life and increased power conservation.
