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. 1.1 Scope of this document In this document, a description is given of the UBA20260 demo boards for 230 V and 120 V mains voltages using the UBA20260 power IC. A description is provided, supported by a set of measurements to show the demo boards characteristics. The UBA20260 circuit is a half-bridge driver IC setup to drive a typical 23 W burner with a lamp current of about 240 mA. Similar lamp types with a nominal lamp power of 20 W can also be driven. The total power drawn from the mains is about 23 W at a nominal mains voltage of 230 V or 120 V (RMS). The UBA20260 board can easily be configured to drive different Compact Fluorescent Lamps (CFL) of different power ratings. Driving different CFL is possible by changing the inductor tap and installing a different lamp capacitor. The UBA20260 demo board is not recommended for driving lower voltage linear lighting lamps like the T5 or the T8. For these types of lamps the UBA2014, UBA2021 or UBA2016 are the best options. The IC is able to drive lamps up to 23 W provided the maximum junction temperature of the IC is not exceeded. There are no THD-requirements for mains powers lower than 25 W so that a pre-conditioner function is obsolete. Remark: Unless otherwise stated all voltages are AC. The circuit is set up to perform a preheat so the lamp switches on approximately 1 s after the mains voltage is applied to the board. Lamp current boost value is approximately 1.5. For detailed design steps, on the 18 W lamp solution or how to setup lamps with other power ratings see Ref. 2. The mains voltage operating range is either set for 90 V to 130 V or 200 V to 250 V (RMS) depending on the board ordered. The ICs are intended as cost-effective step-dimmable solutions to drive CFL with an integrated ballast (CFLi). Therefore, the ICs are equipped with a thermal, coil saturation, over-power and OverCurrent Protection (OCP) and a lamp strike failure time-out. Remark: If the UBA20260 is used in a non-integrated ballast or a Matchbox type of ballast, an external lamp detection circuit is required. In addition, the standard circuit must include extra End Of Life (EOL) protection. Additional circuits can be set up to trigger the external power-down on the CP pin.

Connecting the lamp and mains supply 4.2 External 6-pin controller connector The demo board is equipped with an external control connector intended to control the UBA20260 by a microcontroller or other external control logic. See Figure 6. To be able to control the dimmer input TP1 properly, remove the SMD resistor R8. The connector carries 4 signals, two of which are supply lines, the dimmer input and the short CP pin signal (CPS). 4.2.1 TP4 the CSP/UBA_ON pin Tp4 the CSP/UBA_ON is a pin that offers multiple functions. For the 120 V version this pin is used to provide a differential gain path to the UBA20260. It cannot be used as an input or output. UM10499 User manual All information provided in this document is subject to legal disclaimers. Rev. 1 — 30 September 2011 © NXP B.V. 2011. All rights reserved. 7 of 25 UM10499 NXP Semiconductors 230 V and 120 V reference design using UBA20260 This pin can be used as an external shutdown function when the UBA20260 is in the burn state. To set up for external shutdown, remove the differential gain function, R38, R36 and C29 and install R29. The CPS pin can be directly short-circuited to ground (TP2 GND) or via an open collector output of a microcontroller. Short circuiting the CP pin to ground sets the UBA20260 in Power-down mode. This state continues as long as the IC is supplied via its VDD pin, consumption is less than 220 A. The current from the CPS pin is < 50 mA. To end power-down, power cycle the board or short the TP3 (VDD) pin to ground. The current from this pin is < 500 A when continuously shorted to ground (TP2). When the VDD pin is shorted to ground, the 470 nF VDD capacitor is discharged. To prevent large discharge currents, install a 1 k resistor in series with the capacitor. The VDD pin (TP3) has only a limited supply capability for external logic. Do not load this pin by more than 2 mA. 6-pin controller connector aaa-000322 Fig 6. External control 6-pin controller connector 4.2.2 TP5 and TP6 End of life TP5 CPS_EOL is the out put of the external EOL circuit on the demo board. Connect this pin to TP4 CSP/UBA_ON to use the external EOL. Setup TP for external shutdown for this application. See Section 4.2.1. TP6 is the input of the external EOL circuit. Use the auto transformer winding on T1 in order to use the external EOL. Therefore, remove R30 to R33 and install R39. In addition, hardwire TP6 to T1 pin 2 and hardwire T1 pin 3 to ground.

CFL controller board 4.3 Using the auto transformer The inductor supplied with this board accommodates an auto transformer winding. The auto transformer winding lowers or raises the working voltage across the resonant tank capacitor. In addition, it increases the overall efficiency by up to 30 %. Adjust the auto transformer to the lamp voltage to the lamp type connected to the board for correct operation. See Ref. 2. Table 1 shows how to set the auto transformer. The lamp voltage is the nominal lamp voltage at the rated lamp power when the lamp is not dimmed. The auto transformer is set up as follows for most of the lamps: Table 1. Resistor programming Lamp voltage Description Placement Placement Placement R39 R30+R33 R31+R32 Vlamp < 95 V Raise voltage across Cres. The voltage source charge pump energy transfer to buffer capacitor is increased 95 V < Vlamp < 110 V No auto transformer. Select upon lamp voltage during deep dimming performance Vlamp > 110 V Lower voltage across Cres. The voltage source charge pump energy transfer to buffer capacitor is decreased If the lamp voltage is between 95 V and 110 V, the use of an auto transformer is not necessary. However, set-up and use the auto transformer in the following situations: • where the lamp voltage is too high at low dimming levels • when the bus voltage exceeds the buffer capacitor voltage rating UM10499 User manual All information provided in this document is subject to legal disclaimers.

SO16 package thermal considerations The UBA20260 in the SO16 package is mounted on a separate board perpendicular onto the main signal PCB. The reason for this is that the IC is not directly subjected to the thermal radiated heat of the lamp. In this way, distance is created between lamp filaments and the IC. The horizontal signal PCB acts as a heat shield for thermal radiated heat. The PCB is mounted horizontally into a lamp base for most applications. However, the UBA20260 is an SMD component and means the IC is very close to the lamp filaments. The lamp filaments would directly radiate heat onto the IC and limit the IC drive capabilities. Therefore, it is recommended to either mount some form of heat shield between the lamp filaments and the PCB. Alternatively, mount the PCB vertically into the lamp socket to increases the distance between the IC and lamp filaments. aaa-000726 Fig 9.
