Product Details

The LTC7050 dual monolithic power stage fully integrates high speed drivers with low resistance half-bridge power switches plus comprehensive monitoring and protection circuitry in an electrically and thermally optimized package. With a suitable high frequency controller, this power stage forms a compact, high current volt-age regulator system with state-of-the-art efficiency and transient response.

SilentMOS technology utilizes second generation Silent Switcher 2 architecture reducing both EMI and switch-node voltage overshoot while maximizing efficiency at high switching frequencies.

High speed current sensing provides low latency switch current information, enabling tight current balancing and immediate overcurrent protection. Thermally-enhanced packaging provides dual 40A rated continuous output current capability.

APPLICATIONS

  • High Current Servers and Workstations
  • Networking/Telecom Microprocessor Supplies
