Introduction 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. Remark: Galvanic isolation of the mains phase using a variable transformer is always recommended. These devices can be recognized by the symbols shown in Figure 1. 019aaa691 019aaa690 a. Isolated Fig 1. b. Not isolated Variac isolation symbols 1.1 General description The UBA2024AP circuit is a half-bridge driver IC, which has been set-up to drive a standard PLC-18W, G24q-2 socket based lamp or similar lamp types with a nominal lamp power of 16.5 W. The total power drawn from the mains is about 18 W at a nominal mains voltage of 230 V (RMS); 50 Hz or 120 V (RMS); 60 Hz. The board can easily be configured to drive different Compact Fluorescent Lamps (CFL) of different power ratings as some design examples will show by changing the inductor tap and applying a different lamp capacitor. The UBA2024AT demo board is not recommended for driving lower voltage linear lighting lamps like the T5 or the T8. The UBA2021 is the optimal option for these type of lamps. The IC is able to drive lamps up to 22 W provided the maximum junction temperature of the IC is not exceeded. There are no THD requirements for mains power lower than 25 W, so a pre-conditioning function is obsolete. The circuit is set-up to perform a quasi preheat so the lamp will turn on approximately 0.7 s after the mains voltage has been applied to the board. For detailed design steps on the 18 W lamp solution or how to set-up lamps with other power ratings please consult the application note AN10713 “18 W CFL lamp design using UBA2024 application development tool and application examples”. The mains voltage operating range is either set for 90 V to 130 V (RMS) or 200 V to 250 V (RMS), depending on the ordered board. Both voltage range strappings have been incorporated in one layout of the board. This makes easier to set-up the same board with a different voltage range.

All rights reserved. 3 of 16 UM10388 NXP Semiconductors UBA2024AP DIP8 18 W demo board The IC is not equipped with a thermal protection or open lamp detection because the IC is intended as a cost-effective solution to drive CFLs with an integrated ballast (CFLi). The demo board has been set-up around a detachable lamp, so a protection circuit has been added to the board that will set the IC to a safe mode of operation when there is no lamp attached to the circuit. This circuit is not needed in a typical CFL application. Remark: If the UBA2024AP is used in a non-integrated ballast or a 'matchbox' type of ballast, the protection circuit is required.

The board has been designed to accommodate layouts for 120 V (AC) or 230 V (AC) line voltages. An ordered board is preset for a certain line voltage. The labeling on the board for the mains voltage connector has been designed in such a way that the correct line voltage label becomes visible when the two way screw terminal block for the mains voltage is soldered to the proper position. W5 K3 When a board for a specific line voltage is ordered, the customer is free to set it up for a different line voltage. Make sure that the position of the two way screw terminal block is changed accordingly, so the correct mains voltage label becomes visible.

Connecting the 120 V (AC) mains demo board 3.2 Lamp inductor selection The inductor supplied with this board has been made to accommodate three inductors in one. This makes setting up the board for different lamp powers easier, since it is much easier to change the lamp capacitor than the lamp inductor. It also speeds up the design time (see Section 5 and the application note AN10713). Figure 5 shows how to select a different lamp inductor. The inductor can be set for 2.1 mH (default setting on delivery for the 18 W lamp), 2.7 mH, and 3.1 mH, The saturation current for the 2.1 mH inductor setting is 1.1 A at 125 C ambient. Remark: Only short one jumper, otherwise the inductor windings become shorted. 3.1 mH 2.1 mH 2.7 mH default setting 3322-029-91201 Fig 7.

Conduction emissions test Conducted emissions have been measured in neutral and line wires using a pre-compliance test setup, considering the limits for lighting applications, i.e. EN55015. The measurements have been performed at 230 V (AC) line voltage. The results are shown in Figure 8 and Figure 9. The emission level is below both the quasi peak and the average limits with an acceptable margin. The measurements taken are only valid for this particular board design. The board layout can be used as a guide to set-up the actual design, but there is no absolute guarantee that the final product will pass the conducted EMI test. The board shown is only part of a total product (including housing and wiring) that needs to pass. 019aab388 Fig 8.
