Thanks, Joe, and good afternoon. Second quarter revenues were $106.8 million in line with our guidance and up 4% year-over-year in spite of a challenging demand environment. The year-over-year growth was driven by communications and industrial categories. Industrial grew high single digits year-over-year and was our largest revenue category in the quarter at 35% of sales.
We saw a combination of the recovery and broad-based industrial applications as well as incremental growth across diverse range of verticals, where trends like home and building automation, electrification are creating opportunities for our products. On the automation side, we are seeing growth in USB wall outlets, smart meters, and other IoT applications such as network thermostats and door locks, where high reliability, compact size, low standby power consumption are critical factors.
Meanwhile, electrification is creating opportunities in applications like lawn equipment, vacuum cleaners, and personnel transportation such as scooters and e-bikes, where rechargeable batteries are replacing traditional power sources. Growth in these areas was offset somewhat by lower revenues from high-power due to softer demand in the energy exploration and a slowdown in infrastructure projects due to the pandemic. However, high power has its own attractive verticals with strong long-term growth prospects including renewable energy, long distance DC transmission, and electric transportation.
Our gate drivers are in use today in electric buses and locomotives and are in testing at several automotive OEMs and Tier 1 suppliers for drivetrain and charging applications in next generation electric
