Description for the LM25122-Q1

The LM25122 is a multiphase capable synchronous boost controller intended forhigh-efficiency synchronous boost regulator applications. The control method is based upon peakcurrent mode control. Current mode control provides inherent line feed-forward, cycle-by-cyclecurrent limiting and ease of loop compensation.

The switching frequency is programmable up to 600 kHz. Higher efficiency is achieved bytwo robust N-channel MOSFET gate drivers with adaptive dead-time control. A user-selectable diodeemulation mode also enables discontinuous mode operation for improved efficiency at light loadconditions.

An internal charge pump allows 100% duty cycle for high-side synchronous switch (Bypassoperation). A 180º phase shifted clock output enables easy multi-phase interleaved configuration.Additional features include thermal shutdown, frequency synchronization, hiccup mode current limitand adjustable line undervoltage lockout.
