Description:

Wide Range Synchronous Buck Controller

Features

* New, similar products available:
* LM5148 80-V synchronous buck controller with ultra-low IQ and DRSS
* LM5149 80-V synchronous buck controller with ultra-low IQ and AEF
* Emulated peak current mode
* Wide operating range up to 100 V
* Low IQ shutdow

Applications

* control method is based upon current mode control using an emulated current ramp. Current mode control provides inherent line feed-forward, cycle-bycycle current limiting, and ease-of-loop compensation. The use of an emulated control ramp reduces noise sensitivity of the pulse-width modulation circ
