Description
AI
The LTC7051 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 voltage 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 70A rated output continuous current capability.ApplicationsHigh Current Servers and WorkstationsNetworking/Telecom Microprocessor SuppliesSmall Form-Factor POL Converter
