The TPS51120 is a highly sophisticated dual, synchronous step-down controller. It is a full featured controller designed to run directly off a three-or-four cell Li-ion battery and provide high-power and 5V and/or 3.3V standby regulation for all the downstream circuitry in a notebook computer system. High-current, 100mA, 5V or 3.3V on-board linear regulators have glich-free switch over function to SMPS and can be kept alive independently during standby state. The pseudo-constant frequency adaptive on-time control scheme supports full range of current mode operation including simplified loop compensation, ceramic output capacitors as well as seamless transition to reduced frequency operation at light-load condition. Optional D-CAP mode capacitors allows further reduction of external compensation parts. Dynamic UVP supports VIN line sag without latch off by hitting 5V UVP. No negative voltage appears at output node during UVLO, UVP, and OCP, OTP or loss of VIN.
