封装:N/A 产品备注:CFL半桥功率芯片 产品品牌:照明IC->PHLIPS UBA2024; Half-bridge power IC for CFL lamps General description The UBA2024 is a high-voltage monolithic integrated circuit made in the EZ-HV SOI process. The IC is designed for driving CFL lamps in a half-bridge configuration. 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 percent duty cycle, the oscillator signal is passed through a divider before being fed to the output drivers. Features Integrated half-bridge power transistors Integrated bootstrap diode Integrated low-voltage supply Maximum voltage of 550 V Adjustable oscillator frequency Soft start Minimum glow time control. Applications Driver for any kind of load in a half-bridge configuration Especially for electronically self-ballasted Compact Fluorescent Lamps (CFL) for lamp currents up to 220 mA (RMS) under the restriction that the maximum junction temperature is not exceeded.
