LM5122ZPWPT, Switching Controllers 3-65V Wide Vin, Current Mode Synchronous Boost Controller with Multiphase Capability 24-HTSSOP -40 to 125
Power\Power Management ICs\Switching ControllersLM5122/LM5122-Q1 Synchronous Boost Controllers
Texas Instruments LM5122/LM5122-Q1 Synchronous Boost Controllers are multiphase capable controllers intended for high-efficiency synchronous boost regulator applications. The control method is based upon peak current mode control. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation. The switching frequency is programmable up to 1MHz. Higher efficiency is achieved by two robust N-channel MOSFET gate drivers with adaptive dead-time control. A user-selectable diode emulation mode also enables discontinuous mode operation for improved efficiency at light load conditions.
