NXP公司的UBA2015P是能驱动管灯(TL)和紧凑型荧光灯(CFL)的高压集成电路,包括荧光灯控制模块,半桥驱动器,内置的临界导通模式PFC控制器/驱动器以及多种保护机制.电源电压高达600V,可调整预热时间和预热电流以及点火失效检测,主要用在荧光灯照明电源.本文介绍了UBA2015P主要特性和优势, UBA2015P评估板指标,方框图,电路图和材料清单.
The UBA2015P is a high voltage Integrated Circuit (IC) intended to drive fluorescent lamps with filaments such as Tube Lamps (TL) and Compact Fluorescent Lamps (CFL) in general lighting applications. The IC comprises a fluorescent lamp control module, half-bridge driver, built-in critical conduction mode Power Factor Correction (PFC) controller/driver and several protection mechanisms. The IC drives fluorescent lamp(s) using a half-bridge circuit made of two MOSFETs with a supply voltage of up to 600 V. The UBA2015P is designed to be supplied by a start-up bleeder resistor and a dV/dt supply from the half-bridge circuit, or any other auxiliary supply derived from the half-bridge or the PFC. The supply current of the IC is low. An internal clamp limits the supply voltage.
