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.
