Introduction

The PMIC - Voltage Regulators - Linear, MC33762DM-3030RG (hereafter referred to as MC33762) is a part of the MC33762 series of linear voltage regulators. Its main functions include voltage measurement, voltage regulation and overload protection. Its job is to take an input voltage and regulate it to the required output voltage and current levels. This part has a wide range of applications in industrial, automotive, medical and consumer electronics fields, and is increasingly being used in automotive battery control systems.

Application field

The MC33762 has many advantages over other components in the same series. For example, it can handle a wide input voltage range from 3.2V to 20V and can provide up to 30V of output voltage. It is also designed for low power consumption and features an adjustable switching frequency of up to 1.2MHz. The device also features an integrated overvoltage protection and undervoltage lockout.

The MC33762 is suitable for a variety of conditions, including high temperature and hazardous environments. It can be used in battery control systems, uninterruptible power supplies (UPS) and automotive battery protection systems. It can be used in high voltage DC-DC converters and power supplies, where its load regulation and ripple rejection characteristics make it ideal for these applications. It is also used in electric vehicles, solar applications and power converters.

The MC33762 is also suitable for various medical applications, such as in medical diagnostic equipment and medical imaging systems. Its low quiescent current ensures low battery drain in such applications. Additionally, its high efficiency makes it great for energy harvesting systems where energy efficiency is of utmost importance.

Working principle

The MC33762 works by taking an input voltage and regulating it to the required output. It does this by controlling the output voltage using feedback from the output voltage and current terminals. The device also has a programmable overload protection current limit circuit which prevents damage to the part from excessive current flow.

The regulation loop of the MC33762 consists of a reference voltage, an error amplifier and a driver transistor. The reference voltage is a reference voltage that is set by the user. The error amplifier compares the output voltage of the circuit to the reference voltage and produces an output signal. This signal is used by the driver transistor to regulate the output voltage. The driver transistor also has a current limit input that is used to protect against excessive current flow.

Conclusion

The MC33762DM-3030RG is a versatile linear voltage regulator. It is designed to handle a wide input voltage range and can provide up to 30V of output voltage. It boasts low power consumption and an adjustable switching frequency of up to 1.2MHz. The device also features integrated overvoltage protection and undervoltage lockout for added safety. It finds use in many applications like battery control systems, uninterruptible power supplies (UPS) and automotive battery protection systems, as well as medical and energy harvesting applications. Finally, thanks to its regulation loop and current limit input, it can also provide excellent overload protection.
