Overview
LM3489/LM3489Q Hysteretic PFET Buck Controller with Enable Pin June 23, 2008 LM3489/LM3489Q Hysteretic PFET Buck Controller with Enable Pin General Description The LM3489 is a high efficiency PFET switching regulator controller that can be used to quickly and easily develop a small, cost effective, switching buck regulator for a wide range of applications.
The hysteretic control architecture provides for simple design without any control loop stability concerns using a wide variety of external components.
The PFET architecture also allows for low component count as well as ultra-low dropout, 100% duty cycle operation.
Another benefit is high efficiency operation at light loads without an i...
