LTC7051-1 SilentMOS Smart Power Stage in 5mm × 8mm LQFN
Product Details
The LTC7051-1 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 65A rated output current capability.
