The LM5122 is a multiphase 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 feedforward, 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 Nchannel MOSFET gate drivers with adaptive deadtime 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 180º phase shifted clock output enables easy multiphase interleaved configuration. Additional features include thermal shutdown, frequency synchronization, hiccup mode current limit and adjustable line undervoltage lockout.
