Safety warning WARNING Lethal voltage and fire ignition hazard The non-insulated high voltages that are present when operating this product, constitute a risk of electric shock, personal injury, death and/or ignition of fire. This product is intended for evaluation purposes only. It shall be operated in a designated test area by personnel qualified according to local requirements and labor laws to work with non-insulated mains voltages and high-voltage circuits. This product shall never be operated unattended.. Specification The demo board is powered by AC mains voltage. Avoid touching the board when power is applied. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Table.

5 UM059 UBA06AT HFTL demo board with boost and dimming 4. Board description Refer to Figure. The demo board input section comprises a fuse, surge protection against fast AC transients, EMI filter, double-side rectifier and Power Factor Correction (PFC). The output of the PFC connects to a buffer electrolytic capacitor to supply the half-bridge circuit which is connected to the lamp. The PFC and half-bridge circuit is controlled by the UBA06AT controller IC. An input is provided to control dimming of the lamp light output. The PFC is implemented as an up-converter in boundary conduction mode. The resonant circuit is voltage fed by the half-bridge which comprises two NMOST transistors. The resonant circuit includes a transformer for electrode heating. The ballast circuit design used in the demo board is typical for driving most lamps rated above 5 W, and is proven to be a cost-effective application.

If no dimming is required, the dimmer input must be left floating. live neutral earth V to 0 VDC brown blue green/yellow violet(+) grey( ) BALLAST red red blue blue LAMP 09aaa587 Fig 0. Wiring diagram The earth/chassis connection must be connected to the earth tag J shown in Figure. There is no provision for an earth connection on the mains connector. If a metal fixture is used, it must also be connected to the earth tag J. 6. Dimming without external voltage source The ballast circuit is designed to be dimmed with a voltage source from V to 0 V DC. However, it is possible to dim with an external potentiometer of 470 k. This function is intended for demonstration purposes only. The potentiometer must be connected to pin (grey wire) and pin (violet wire) of connector J.
