CS5421
Dual OutofPhase
Synchronous Buck
Controller with Remote
Sense
The CS5421 is a dual N
channel 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 CS5421 features
out
of
phase synchronization between the channels, reducing the
input filter requirement. The CS5421 also provides undervoltage
lockout, Soft Start, built in adaptive FET non
overlap and remote
sense capability. The part is available in a 16 Lead SO Narrow package
allowing the designer to minimize solution size.
