IC revision1.01

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 withminimized 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 isgreater 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 programmedto proper level to meets the characteristics of fluorescent lamp. The over-voltage, overcurrent, 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.

Features

  • Only four pins realize PFC function.
  • Ton control.
  • Boundary Conduction Mode operation.
  • Less peripheral components.
  • Over voltage and over current protection.

Remarks:L1=4.7mH,L2=6.8mH,L3,L4=2.2mH,L5=2.2mH And LB1 Inductor used Refer page no.3

Typical applications

  • Compact fluorescent lamp ballast
  • Tube fluorescent lamp ballast
