Power-Saving Flat Panel VCOM Buffer Amplifier

Exar Corp. recently announced a next-generation VCOM control product based on patent-pending innovative architecture. The iML2911 provides a solution to add two additional power supply voltages readily available in panel electronics. The device employs sensing circuitry for VCOM output load requirement and automatically switches between multiple supply voltage combinations. This results in 50% savings of energy for still images and 25% to 30% savings for dynamic display images without affecting the quality. The iML2911 is also advantageous for use in TV panel applications, where heat dissipation from VCOM buffer devices is a major concern for panel and set makers, as local heating can negatively affect image quality.Exar_iML2911

Summary of features:

  • Significant power savings for managing VCOM voltage level
  • Patent-pending, integrated sensing circuitry
  • Up to 12V VCOM voltage range

The iML2911 is currently available in an eight-pin TDFN package and in a nine-ball CSP. Pricing starts at $0.45 in 10,000-piece quantities. Device samples and evaluation circuit boards are currently available online or from your local sales office.
