3 Description
The LM5122 is a multi-phase capable synchronous boost controller 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 1 MHz. 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.
An internal charge pump allows 100% duty cycle for high-side synchronous switch (bypass operation). A 180° phase shifted clock output enables easy multi- phase interleaved configuration. Additional features include thermal shutdown, frequency synchronization, hiccup-mode current limit, and adjustable line undervoltage lockout.
