UC3832DWG4 is a linear voltage regulator controller IC with a full featured device designed for clock uses in switching power supplies. It operates with a wide range of voltage ratings (3.3V to 40V) and provides up to 600mA of current. The UC3832DWG4 is designed with a wide range of protection features and is RoHS compliant. The device is available in a miniature SOIC-8 package with an 8-lead plastic molded power dip.
The UC3832DWG4 is an easy to use device that provides the user with good flexibility for applications, including AC-DC and DC-DC conversion, lighting applications, battery control systems and DC-DC converter control. It allows the user to set the supply voltage to any within the devices maximum ratings. The device also has a low output voltage drop-out (Vdroop) for improved efficiency in many applications.
Application Field
The UC3832DWG4 is suitable for a wide range of applications including AC-DC and DC-DC conversion, lighting applications, battery control systems and DC-DC converter control. The device can also be used in mobile applications, such as notebook computers, cellular phones and other portable devices, where high efficiency and low power consumption are critical. The UC3832DWG4 is also suitable for use in any system where a wide output voltage range and good regulation is desired.
Working Principle
The UC3832DWG4 is a linear voltage regulating controller IC with an adjustable output reference of 3.3V to 40V. It is designed around a linear system architecture and is optimized for low power consumption and high output current capability. It provides the user with adjustable output voltage and good output current regulation in an easy to use package. The device utilizes an onboard voltage reference, which can be trimmed to adjust the output voltage range. This reference voltage is then compared to a voltage divider connected to the output and when the output voltage is higher than the reference, the device reduces the current to the output.
The UC3832DWG4 has a wide range of protection features. It has a built in sense resistor to monitor over current conditions, as well as an over temperature shut down function. The device also has a reverse current protection feature which detects when the output voltage is higher than the input voltage and shuts down the device in order to protect the load from reverse current. There is also an active clamp circuit built into the device which prevents shoot-through in the output MOSFETs.
The UC3832DWG4 is an ideal solution for a wide range of applications requiring good voltage regulation, high output current capability, and low power consumption. It is available in a small 8-pin SOIC package and is RoHS compliant.
