NCP5422A
Dual OutofPhase
Synchronous
Buck Controller
with Current Limit
The NCP5422A is a dual Nchannel synchronous buck regulator
controller. It contains all the circuitry required for two independent
buck regulators and utilizes the V
2
control method to achieve the
fastest possible transient response and best overall regulation, while
using the least number of external components. The NCP5422A
features outofphase synchronization between the channels,
reducing the input filter requirement. The NCP5422A also provides
undervoltage lockout, Soft Start, built in adaptive nonoverlap time
and hiccup mode overcurrent protection.
