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.
