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.

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
