DESCRIPTION
The EVHR2000-S-00A is an evaluation board
for the HR2000. 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 EVHR2000DS-00A is designed to drive
16W fluorescent lamp. With the simple and
sufficient on-time control APFC, the demo
board provides 400V DC bus voltage for ballast
and clean load for Grid. The power factor is
greater than 0.9 in all input voltage range. The
over-voltage and over-current protection of PFC
stage are integrated to ensure the safety.
The half-bridge ballast controller directly drives
two MOSFETs to control the fluorescent lamp.
The preheat and ignition time are programmed
to proper level to meets the characteristics of
fluorescent lamp. The over-voltage, over-
current, capacitive-mode, and end-of-life (EOL)
protection are all integrated.
The EVHR2000DS-00A meets EN55015 EMI
standard. And THD meets IEC61000-3-2 Class
C standard.

Warning:
Although this board is designed to satisfy safety
requirements, the engineering prototype has not been agency
approved. Therefore, all testing should be performed using an
isolation transformer to provide the AC input to the prototype
board.
