1 / 6 page ![]() Data brief For further information contact your local STMicroelectronics sales office. October 2011 Doc ID 022333 Rev 1 1/6 6 STEVAL-ILH004V1 70 W electronic ballast for metal halide lamp (HID) based on the L6382D5 and ST7FLITE49K2 Features ■ Minimum mains voltage (rms value): 85 V ■ Maximum mains voltage (rms value) : 265 V ■ Minimum mains frequency( fmin): 47 Hz ■ Expected bridge efficiency (H-bridge): 95% ■ Rated lamp power (Plamp) : 70 W ■ Rated output power: 73 W ■ Output current: 0.18 A ■ Regulated DC output voltage (Vout ): 410 V ■ Maximum output low-frequency Vout ripple: 20 V ■ PFC minimum switching frequency: 30 kHz ■ Expected PFC efficiency 96 % ■ Expected input section efficiency: 99% ■ Expected power factor: 0.99 ■ RoHS compliant Description The STEVAL-ILH004V1 demonstration board implements a digital ballast for a 70 W HID lamp (sodium or metal halide) used in general lighting applications. The ballast is composed of a boost converter (power factor controller PFC) working in transition mode and an inverter composed of a half-bridge that drive the lamp in low-frequency square wave. Both the half-bridge and the PFC stage are managed by the ST7LITE49K2 that controls the L6382D5, activating all the power switches. STEVAL-ILH004V1 www.st.com |
