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. https://elecena.pl/product/30542938/3-65v-wide-vin-current-mode-synchronous-boost-controller-with-multiphase-capability-pwp-20-40-to-125 2026-07-31 https://elecena.pl/product/30542938/3-65v-wide-vin-current-mode-synchronous-boost-controller-with-multiphase-capability-pwp-20-40-to-125 2026-10-06
