UBA2024 Half-bridge power IC for CFL lamps Rev. 6.2 — 1 November 2010 Product data sheet 1. General description The UBA2024 is a family of high-voltage monolithic Integrated Compact Fluorescent Lamp (CFL) drivers for a large range of lamp powers. Specific versions are optimized for 230 V and 110 V mains supplies. The product family integrates full CFL controller functionality with high voltage half-bridge transistors. All products in the UBA2024 family are pin-to-pin compatible enabling a single application design covering a wide range of power ratings. The IC features a soft start function, an adjustable internal oscillator and an internal drive function with a high-voltage level shifter for driving the half-bridge. To guarantee an accurate 50 % duty cycle, the oscillator signal is passed through a divider before being fed to the output drivers. 2. Features and benefits The common feature set includes: high power efficiency a high integration level with low component counts enabling small form factor electronic ballast integrated bootstrap diode soft start function minimum glow time control integrated low-voltage supply adjustable operating frequency as a result of the embedded oscillator an accurate 50 % duty cycle provided by an embedded oscillator signal integrated half-bridge power transistors an internal drive function with a high-voltage level shifter up to 550 V (300 V for the UBA2024BP and UBA2024BT) 3. Applications Driver for any kind of half-bridge configured load up to 23 W, provided that the maximum junction temperature is not exceeded Designed for electronically self-ballasted CFL lamps NXP Semiconductors UBA2024 Half-bridge power IC for CFL lamps 4.

Functional description 7.1 Supply voltage The UBA2024 does not require an external low-voltage supply as the mains supply voltage applied to pin HV powers it. The IC derives its own low supply voltage from this for its internal circuitry. 7.2 Start-up state With an increase of the supply voltage on pin HV, the IC enters the start-up state. In the start-up state the high-side power transistor is not conducting and the low-side power transistor is switched on. The internal circuit is reset and the capacitors on the bootstrap pin FS and low-voltage supply pin VDD are charged. Pins RC and SW are switched to ground. The start-up state is defined until VDD = VDD(startup). 7.3 Sweep mode The IC enters the sweep mode when the voltage on pin VDD > VDD(startup). The capacitor on pin SW is charged by ISW and the half-bridge circuit starts oscillating. The circuit enters the start-up state again when the voltage on pin VDD < VDD(stop). The sweep time (tsweep) is determined by the charge current (Ich(sw)) and the external capacitor (CSW). Typical the total sweep time set by CSW is: t sweep = C SW ( n F ) × 10.3 m s During the sweep time the current flowing through the lamp electrodes performs some preheating of the filaments. See Figure 5. (1) 7.4 Reset A DC reset circuit is incorporated in the high-side driver. The high-side transistor is switched off when the voltage on pin FS is below the high-side lockout voltage Vfloat(UVLO). 7.5 Oscillation The oscillation is based upon the 555-timer function. A self oscillating circuit is made with the external resistor ROSC and the capacitor COSC (see Figure 4). To realize an accurate 50 % duty cycle, an internal divider is used. This reduces the bridge frequency to half the oscillator frequency. The output voltage of the bridge will change at the falling edge of the signal on pin RC. The design equation for the half-bridge frequency is: 1 f osc = ---------------------------------------k × R OSC × C OSC An overview of the oscillator signal, internal LS and HS drive signals and the output is given in Figure 4.

Oscillator, drivers and output signals When entering the sweep mode (VSW = 0 V), the bridge oscillator starts at 2.5 times the nominal bridge frequency and sweeps down to the nominal frequency (bridge), set by ROSC and COSC. During the sweep mode the amplitude of the RC oscillator on pin RC, will swing between Vtrip(osc)low and VSW + 0.4Vtrip(osc)high. The amplitude of the RC oscillator will continue to increase until VSW + 0.4Vtrip(osc)high = Vtrip(osc)high, this determines the end of the sweep time. The voltage on pin SW however will continue to rise until it reaches supply voltage level. During this continuous decrease in frequency, the circuit approaches the resonance frequency of the load, and this causes a high voltage across the load, which ignites the lamp. The sweep to resonance time should be much larger than the settling time of the supply voltage on pin HV, to guarantee that the full high-voltage is present at the moment of ignition. See Figure 5.
