Product Details
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.
APPLICATIONS
- High Current Servers and Workstations
- Networking/Telecom Microprocessor Supplies
