Dual Out−of−Phase
Synchronous
Buck Controller
with Current Limit
The NCP5422A/3 is a dual N−channel synchronous buck regulator
controller. It contains all the circuitry required for two independent
buck regulators and utilizes the V2
t control method to achieve the
fastest possible transient response and best overall regulation, while
using the least number of external components. The NCP5422A/3
features out−of−phase synchronization between the channels,
reducing the input filter requirement. The NCP5422A/3 also provides
undervoltage lockout, Soft−Start, built in adaptive non−overlap time
and hiccup mode overcurrent protection.
