MIC38C45AYMM-TR

The MIC38C45AYMM-TR is an advanced BiCMOS voltage regulator family from Microchip Technology Inc. It is part of the Power Management IC (PMIC) portfolio, specifically being a DC/DC Switching Controller. The features and capabilities make it ideal for applications requiring efficient, cost-effective and scalable power management solutions.

The MIC38C45AYMM-TR is a high-efficiency, low-power voltage regulator designed to operate across a wide range of voltages and temperatures. It is designed to provide a reliable switching power supply system with a switching frequency up to 1 MHz. The device incorporates a variety of features, including low output current, low thermal resistance and high switching speed, helping it to achieve excellent efficiency, superior reliability and long life expectancy.

The purpose of the MIC38C45AYMM-TR is to regulate the voltage across an output voltage range from 0.25V to 63V. The device can regulate an output voltage between 0.25V and 63V and has an operating temperature range of -40°C to +85°C. It provides up to 5A of output current and has a wide range of protection features such as thermal shutdown in the event of over-temperature, output over-voltage, output under-voltage and output current limit.

The MIC38C45AYMM-TR operates with feedback control, where an external error amplifier is used to compare the output voltage to an internal reference voltage. The output voltage is then adjusted accordingly to achieve the desired level, depending on the value of the feedback components. The device also features two main modes of operation, namely Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM).

The main features of the MIC38C45AYMM-TR include:
