1 / 6 page ![]() Data brief For further information contact your local STMicroelectronics sales office. November 2011 Doc ID 018902 Rev 1 1/6 6 STEVAL-ILH005V2 150 W electronic ballast for HID lamps based on the L6562A and ST7LITE39F2 Features ■ Minimum mains voltage: Vac(min) = 185 V ■ Maximum mains voltage: Vac(min) = 265 V ■ Minimum mains frequency: fmin = 47 Hz ■ Output current: Iout = 0.38 A ■ Rated lamp power: PLamp = 150 W ■ Expected bridge efficiency: η bridge = 95% ■ Regulated DC output voltage (DC value): Vout = 420 V ■ Maximum output overvoltage (DC value): ΔOVP = 50 V ■ Maximum output low-frequency ripple: ΔV outx = 20 V ■ PFC minimum switching frequency: fmin = 28 kHz ■ Expected PFC efficiency: η PFC= 96% ■ Expected input section efficiency: η in= 99% ■ Expected power factor: 0.99 ■ RoHS compliant Description The STEVAL-ILH005V2 demonstration board implements a two-stage electronic ballast for 150 W HID metal halide lamps. The ballast is composed of a boost converter (power factor controller PFC) working in transition mode and an inverter consisting of a full bridge that drives the lamp at low-frequency square wave. The ballast was developed for 185 - 265 Vac 50/ 60 Hz input mains and is able to drive 150 W metal halide and high-pressure sodium lamps. STEVAL-ILH005V2 www.st.com |
