NCP5331

Two−Phase PWM

Controller with Integrated

Gate Drivers

The NCP5331 is a second-generation, two-phase, buck controller

that incorporates advanced control functions to power 64-bit AMD

Athlont processors and low voltage, high current power supplies.

Proprietary multiphase architecture guarantees balanced load-current

sharing, reduces output voltage and input current ripple, decreases

filter requirements and inductor values, and increases output current

slew rate. Traditional Enhanced V

has been combined with an

to the

internal PWM ramp and voltage feedback directly from V

CORE

internal PWM comparator. These features and enhancements deliver

the fastest transient response, reduce output voltage jitter, provide

greater design flexibility and portability, and minimize overall

solution cost.

FT SUFFIX

CASE 873A

Advanced features include adjustable power- good delay,

programmable overcurrent shutdown timer, superior overvoltage

protection (OVP), and differential remote sensing. An innovative

overvoltage protection (OVP) scheme safeguards the CPU during

extreme situations including power up with a shorted upper MOSFET,

shorting of an upper MOSFET during normal operation, and loss of

the voltage feedback signal, COREFB+.
