Description

The HR2000 is a fluorescent lamp ballast controller with PFC function and high voltage half+bridge driver. Only 16pin is used to offer cost effective solutions with minimized external components.The HR2000 can properly drive the two MOSFETs of half+bridge to control fluorescent lamp, ensuring all the features at the same time. The operating frequency is programmable and the sweeping frequency is controlled tolimit the preheat current. The preheat time and ignition time can be smartly set up for types of lamps and applications. Sufficient protection functions are provided for different fault modes such as over voltage, over current, over temperature, capacitive mode, end of life (EOL). Preheat driving signal is offered in preheat state to meet low power loss application which usually needs a MOSFET to cut off filament transformer.The PFC part only uses 4 pins to realize PFC function with On+time (Ton) control at boundary conduction mode (BCM). It is suitable for wideinput range. Over voltage protection and over current protection are integrated for the PFC part.The HR2000 is available in the 16+pin SOIC16 package.
