NCP5424
Dual Synchronous
Buck Controller with Input
Current Sharing
The NCP5424 is a flexible dual N?Channel synchronous buck
controller utilizing V 2 t control for fast transient response and
excellent line and load regulation. This highly versatile controller can
be configured as a single two phase output converter that draws
programmable amounts of current from two different input voltages or

all current from one supply. The NCP5424 can also be configured as
two independent out?of?phase controllers.
Using the NCP5424 in a current sharing input configuration is ideal

for applications where more power is required than is available from
one supply, such as video cards or other plug?in boards. When
configured as a dual output controller, the output of one controller can
be divided down and used as the reference for the second controller.
This tracking capability is useful in applications such as Double Data
Rate (DDR) Memory power where the termination voltage must track
VDD.

The NCP5424 provides a cycle ?to ?cycle current limit on
Controller 2 allowing the system to handle transient overcurrent
events and a hiccup mode overcurrent protection on Controller 1
allowing lossless short circuit protection. In addition, the NCP5424
provides Soft?Start, undervoltage lockout, and built?in adaptive FET
nonoverlap time to prevent shoot through.
