NXP公司的UBA2016A/15/15A 是具有PFC,线性调光和升压功能的600V荧光灯驱动器.IC包含了荧光灯控制模块,半桥驱动器,内置了临界导电模式PFC控制器/驱动器和多种保护机制,电源电压高达600V,火线电压高达390V.本文介绍了UBA2016A/15/15A主要特性和优势,方框图, 基本的PFC应用框图以及多种TL或CFL应用电路, UBA2016AT HFTL演示板主要指标,框图,电路图和材料清单与PCB布局图. UBA2016A/15/15A:600 V fluorescent lamp driver with PFC, linear dimming and boost function The UBA2016A/15/15A are high voltage Integrated Circuits (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 UBA2016A/15/15A are 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. UBA2016A/15/15A主要特性和优势: Power factor correction features: Integrated 4-pin critical conduction mode PFC controller/driver Open and short pin-short protection on PFC feedback pin Overcurrent protection Overvoltage protection Half-bridge driver features: Integrated level-shifter for the high-side driver of the half-bridge Integrated bootstrap diode for the high-side driver supply of the half-bridge Independent non-overlap time Fluorescent lamp controller features: Linear dimming (UBA2016A and UBA2015A only) EOL (End-Of-Life) detection (both symmetrical and asymmetrical) Adjustable preheat time Adjustable preheat current Adjustable fixed frequency preheat (UBA2015 and UBA2015A only) Lamp ignition failure detection Ignition detection of all lamps fat multiple lamps with separate resonant tanks Second ignition attempt if first failed Constant output power independent of mains voltage variations Automatic restart after changing lamps Adjustable lamp current boost at start-up (UBA2016A only) Lamp current control Enable input (UBA2015 and UBA2015A only) Protection Hard switching/capacitive mode protection Half-bridge overcurrent (coil saturation) protection Lamp overvoltage (lamp removal) protection Temperature protection UBA2016A/15/15A应用: Intended for fluorescent lamp ballasts with either a dimmable (UBA2016A and UBA2015A) or a fixed (UBA2015) output and PFC for AC mains voltages of up to 390 V.
