Part Details:

STEVAL-ILH001V1 250 W electronic ballast demonstration board for metal halide lamps based on the L6562 and ST7LITE39F2 Data Brief Features Input voltage: 90 to 265 Vac, 50 - 60 Hz POUT: 250 W Power factor: 0.94 at 230 Vac Full-bridge for output stage working at low frequency to avoid acoustic resonance PFC (power factor correction) implemented using the L6562 PFC controller Total system efficiency up to 94% Current control during warm-up phase Power control during steady state Description STEVAL-ILH001V1 The STEVAL-ILH001V1 demonstration board implements a two-stage electronic ballast for 250 W, HID (high-intensity discharge) metal halide lamps. The ballast features a boost converter (PFC controller) working in fixed OFF-time, and a full-bridge inverter to drive a lamp using a low frequency square wave. The design of the STEVAL-ILH001V1 takes advantage of STMicroelectronics very large product portfolio. ST components used in the design include: PFC drivers, an inverter driver microcontroller, auxiliary power supply, voltage reference, logic part, amplifier, comparators, and power devices such as power MOSFETs, IGBTs, and fast diodes.
