3A Synchronous Buck Regulator
Technical Data
IK5302
Description
The IK5302 is a 18V 3A synchronous step-down
(buck) converter with two integrated High side and Low
side N-LDMOS transistors. The IK5302 implements
current control method which provides high stability during
operation and fast response during abrupt load change.
It operates from a 4.5V to 18V input voltage range and
supplies up to 3A of load current. The IK5302 operates on
fixed 1Mhz frequency.
