LM27241 Synchronous Buck Regulator Controller

The LM27241 is an adjustable 200kHz-500kHz single channel voltage-mode controlled high-speed synchronous buck regulator controller. It is ideally suited for battery powered applications such as laptop and notebook computers. The LM27241 requires only N-channel FETs for both the upper and lower posit.

LM27241 Features

* line feedforward to improve the response to input transients. At very light loads, the user can choose between the highefficiency Pulse-skip mode or the constant frequency Forced-PWM mode. Lossless current limiting without the use of external sense resistor is made possible by sensing the voltage dr
