70 W electronic ballast for metal halide lamp (HID) based on the L6382D5 and ST7FLITE49K2

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.

Key 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
