Introduction HV853K7-G is an integrated PMIC (power management integrated circuit) designed for lighting, ballast controllers and other equipment that requires power management. This PMIC is a highly integrated solution in a single IC package, providing low noise, efficiency, and high integration and cost savings for applications.Application FieldHV853K7-G provides numerous feature sets for the lighting, ballast controller, and other power management applications. The HV853K7-G is well suited for applications from lower wattage to medium wattage lighting, such as LED lighting, CFL lighting, and digital ballast controllers. The power management features of the HV853K7-G are highly integrated, reducing the complexity and cost of designs, thus making it suitable for use in applications ranging from 10 Watts to more than 500 Watts.Furthermore, the HV853K7-G is well suited for powering luminaires in any environment ranging from street lights to home lighting. Other applications like digital displays, portable devices, and spike suppression require efficient power management and the HV853K7-G can ensure their effective operation.Working PrincipleThe HV853K7-G power management IC is designed to work as an integrated solution with a high level of integration. The IC has outputs that include an integrated buck converter, an integrated boost converter, and two separate buck converters. The buck converters provide a low ripple system and all critical parts are included in one IC package.The integrated Buck converter is built with a high-voltage, low-power MOSFET transistor and can provide a maximum output current of 5A. It has two constant output voltages of 18V, 25V, and 36V and is adjustable to cover different voltages.The boost converter supports continuous conduction mode and provides a constant output voltage up to 18V to 24V. It is adjustable to cover different voltage and output current up to 8A. The other two independent buck converters are fixed at 12V and 3.3V. The 3.3V buck converter supports up to 1.5A and is adjustable. The 12V buck converter provides a constant 12V output and a maximum of 2A output signal. ConclusionThe HV853K7-G is an integrated PMIC designed for lighting, ballast controllers and other equipment that requires power management. It provides numerous feature sets for the lighting, ballast controller, and other power management applications. The HV853K7-G is well suited for applications from lower wattage to medium wattage lighting. The IC is also well suited for powering luminaires in any environment ranging from street lights to home lighting. The power management features are highly integrated, reducing the complexity and cost of designs.
