AS1367-BTDT-33 Application Field and Working Principle

The AS1367-BTDT-33 is a three-phase, four-channel, adjustable linear voltage regulator suitable for a wide range of industrial applications. It is primarily intended for use in constant voltage (CV) battery charging applications, motor control, and other similar applications. The device is primarily targeted for powering industrial equipment with low voltage and high current requirements.The AS1367-BTDT-33 is a synchronous buck regulator based on a versatile buck/boost switching topology. This allows for flexibility in terms of input and output voltage range, and also simplifies the design by reducing the number of components required. The device incorporates an adjustable frequency synchronous buck converter, and an adjustable linear voltage regulator output stage, allowing the user to select both the reference voltage and the output voltage.The device utilizes an internal oscillator to control the regulation. The frequency of the oscillator is adjustable, so that the controller can be adjusted to accommodate different input/output voltages. The converter operates as a synchronous buck regulator, allowing reliable regulation while operating in both buck and boost mode. The converter also utilizes a synchronous rectifier, allowing for higher switching efficiency.The adjustable linear output stage utilizes an external sense resistor to detect the current load. This allows for the voltage to be adjusted to ensure that the current that supplies the load does not exceed the rated output current limitation of the device.The device features very low stand-by current, a wide operating temperature range, and over-temperature, over-current and over-voltage protection. It also incorporates an integrated charge pump, which allows for higher voltage settings.In summary, the AS1367-BTDT-33 is a versatile adjustable linear voltage regulator designed to provide precise control of output voltage and current in a wide range of applications. Its adjustable frequency synchronous buck topology allows for greater efficiency and improved transient response when compared to other regulators. The device also features adjustable power settings, integrated protection features, and a low stand-by current. The user can easily adjust both the output voltage and the reference voltage to suit their application\'s specific needs.
