KP35112 is a high performance Buck power switch for wide input range D2D application

Unlike conventional PWM control, there’s no fixed internal  clock  in  KP35112  family  to  trigger  the GATE driver, the switching frequency varies with load  condition.  The  multi-mode  PW M  control  is integrated  to  simplify  circuit  design  and  achieve good line and load regulation without audio noise.The peak current limit varies with load condition for low standby power.

KP35112  integrates  functions  and  protections  of Under  Voltage   Lockout  (UVLO),  Cycle-by-cycle Current    Limiting    (OCP),     FB    Over    Voltage Protection (FB OVP), On-chip Thermal Shutdown, Over Load Protection (OLP), VDD OVP with Auto Recovery Mode Protection, etc.
