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 to

limit 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 wide

input range. Over voltage protection and over

current protection are integrated for the PFC

part.

The HR2000 is available in the 16-pin SOIC16

package.
