DESCRIPTION
The LTC®7051-1 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 switchnode
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.
