Introduction

TL750M12CKCSE3 voltage regulator generally belongs to PMIC (Power Management Integrated Circuit) within Integrated Circuits, which can synchronize to multiple circuits and source, providing power solutions for automotive, industrial and consumer applications. A distinguishing feature of this product is that it uses linear voltage regulation technology and integrates other functions, such as reverse input/output protection and on/off control.

Functional Overview

The TL750M12CKCSE3 is a linear voltage regulator with high-precision voltage and current measurements, direct output voltage sensing, a regulation circuit and protection circuits. It provides 3 A continuous output current under 12 V output voltage, high stability and good ripple performance. It has low thermal resistance and it is designed for automotive and industrial applications. The product employs over-voltage, reverse input/output, short-circuit protection, over-temperature and complex signal control for precise output voltage and current control. The output voltage can be set according to specific requirements.

Applications

TL750M12CKCSE3 is suitable for automotive, industrial and consumer applications, as it has wide input voltage range from 12 V to 30 V, providing a range of operating conditions. It also has a feature of output current range from 0.2 A to 3 A and output voltage range from 0.8 V to 25 V, achieving the ultimate output power of 75 W which makes it suitable for applications like auxiliary power supply and broadcast system.The advantages of this product over other PMIC voltage regulators are that it has a wide operating temperature range (from -40°C to 125°C) ensuring stable performance when used in extreme conditions and fast transient response time, stimulating multiple load switching. Besides, it has power-on/off control and reverse input and output protection.

Working Principle

TL750M12CKCSE3 voltage regulator employs linear voltage regulation technology to measure and regulate the output voltage accurately. Its working principle involves conversion of input voltage to the output voltage through linear voltage regulating technique.The input voltage is first stepped down into smaller voltage. This voltage is then rectified and filtered, which gives a DC voltage. This DC voltage is then compared to a reference voltage from the reference circuit. The error between the two signals is then amplified and converted into a current to drive the output voltage. The linear voltage regulator maintains the output voltage level by making the voltage drop across the output-stage transistors (either MOSFETs or BJT) the same as the reference voltage.TL750M12CKCSE3 provides features like overload protection, reverse input and output, over-voltage, over-temperature and on/off control. The overload protection feature enables system to shut down when the output current goes above a specific threshold, while the reverse input and output protection prevents the destruction of components when the power is connected with wrong polarity. The device can detect and protect the system from the high input and output voltages through its programmable over-voltage protection and detect overheating by shutting down at a particular temperature threshold. The on/off control feature also provides a flexible system configuration with the help of an external switch.

Conclusion

TL750M12CKCSE3 voltage regulator has all the features needed to provide high precision voltage and current control and regulation under all operating conditions. It has wide input voltage, output current and output voltage ranges, resulting in ultimate output power of 75 W which is suitable for wide range of applications. The product also offers overload protection, reverse input/output protection, over-voltage protection and on/off control features to ensure reliable and efficient performance and maximum system protection. Its linear voltage regulation technology can ensure accurate output voltage control and 7-μs transient response time for fast load switching.
