The MIC4782YML-TR switch-mode DC/DC power supply regulator offers efficient and documented fixed voltage regulation suitable for a wide range of applications. It is a cost effective, energy efficient solution for many applications.The MIC4782YML-TR is a monolithic integrated circuit with overvoltage protection features and built-in voltage and current regulation functions. It operates from a 5V to 28V input voltage range and can output up to 1.2A for positive outputs and up to 0.8A for negative outputs.The MIC4782YML-TR is a switching regulator using pulse width modulation (PWM) to convert an input DC voltage accurately to a regulated output voltage. It uses a power MOSFET transistor (Q1) to switch the input voltage to the output voltage, while the inductor (L) and the capacitor (C) control the voltage conversion process. The feedback circuit senses the output voltage at the FB pin, and compares it with a reference voltage generated internally by IC. The feedback circuit will then adjusts the duty cycle of PWM regulation, which enables precise voltage regulation even when the input voltage and load current fluctuate.The MIC4782YML-TR is suitable for applications such as embedded systems, portable devices and other power supply products. It is capable of providing regulated output voltage from 0.6V up to 13.2V with the variation of just 2.5% by an easily adjusted external potentiometer. It also includes several protection features including over-voltage protection up to 14V, short-circuit protection, stable frequency control, and thermal shutdown of the output stage if the internal temperature exceeds 150°C.In terms of features and performance, the MIC4782YML-TR is great for a variety of applications such as powering field-programmable gate arrays (FPGAs), solid-state drives (SSD) and other energy-consuming devices. It is able to provide a highly efficient and stable output voltage even under heavy load current, making it a reliable choice for embedded systems and other energy-limited applications.Furthermore, the MIC4782YML-TR requires very little external components, as it is only necessary to connect the external capacitors, inductors and resistors to the device. This significantly simplifies the design process and reduces system size and cost.Overall, the MIC4782YML-TR is a reliable and cost-efficient solution for designers seeking an efficient, fixed-voltage power supply regulator. It is perfect for embedded systems and portable applications where energy efficiency and reliability are key. Its low-cost, small form factor and high efficiency make the MIC4782YML-TR an ideal choice for a variety of DC/DC switching regulator applications.
