LM2647, LM2 Datasheet - National Semiconductor

LM2647 Dual Synchronous Buck Regulator Controller

The LM2647 is an adjustable 200-500kHz dual channel voltage-mode controlled high-speed synchronous buck regulator controller ideally suited for battery powered applications such as laptop and notebook computers. The LM2647 requires only N-channel FETs for both the upper and lower positions of each s.

LM2647 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 resistors is made possible by sensing the voltage d
