User manual Rev. 2 — 16 September 2010 3 of 25 NXP Semiconductors UM10395 UBA2014 evaluation board 1. Introduction This document describes the UBA2014 evaluation board. The board is designed to be a flexible tool that demonstrates the many different applications that are possible with the UBA2014 fluorescent tube driver. Please note that this board is not a complete ballast design for fluorescent tubes. The default setup is made such that a T5 HE 35W fluorescent lamp can be demonstrated. 2. Safety warnings The board is intended as an evaluation board to build different TL and or CFL applications. To optimize flexibility, almost no protection is built in (except for IC internal protection). The board does not conform with any safety norm. WARNINGS:
- Do not supply voltages to the board without a daughter board correctly inserted. Failing to do so may damage the board.
- Always operate with burner (lamp) connected to the board and connected to the resonant circuit. Failing to do so may damage the board.
- Many parts contain dangerous high voltages. It is necessary to take relevant safety precautions before using this board.
- Do not touch any part of the board during or shortly after operation of the board. 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.
User manual Rev. 2 — 16 September 2010 4 of 25 NXP Semiconductors UM10395 UBA2014 evaluation board 3. Board description The board consists of two separate Printed-Circuit Boards (PCBs). The main board with the resonant circuit and a small daughter board with the UBA2014 IC.
3.1 Daughter board
The daughter board contains the UBA2014 IC with the preheat, sweep and oscillator capacitor, the VDD generation and some other low voltage components. The daughter PCB can be easily replaced in case of damage. Care should be taken that the board is inserted properly. Pin 11 has been removed from the daughter board to prevent the board being inserted incorrectly. Fig 1. Daughter board 019aaa720

3.2 Main board
The main board has all the other necessary circuit to make a Tubular Lamp (TL) or Compact Fluorescent Lamp (CFL) application. The board consists of the following:
- DC and AC input connector
- Dimming input
- 2 sockets for FETs
- 2 different transformers
- Area for experiments
- Connections for up to 4 burners. Fig 2. UBA2014/21 main board with UBA2014 daughter board inserted 019aaa721
User manual Rev. 2 — 16 September 2010 6 of 25 NXP Semiconductors UM10395 UBA2014 evaluation board 4. Schematics The schematics of the daughter board with the UBA2014 IC can be found in Figure 3. The settings for the oscillator and sweep are R1 = 33 kΩ (to pin IREF), C3 = 100 pF (to pin CF) and C1 = 330 nF (to pin CT). This will provide a minimum oscillator frequency of 40.5 kHz and a preheat time of 1.8 s. Fig 3.
