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
Athlon t 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 2 t has been combined with an
internal PWM ramp and voltage feedback directly from V CORE to the
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.
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+.
