HR2000
Fluorescent Lamp HB Driver with PFC
The Future of Analog IC Technology
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.
