KP35062  is  a  high  performance  Switch  Mode Power  Supply  Switcher  for  low  power  off-line application  with  minimum  components  in  typical buck solution. This IC has built-in high break down voltage MOSFET to withstand high surge input.

Unlike conventional PWM control, there’s no fixed internal  clock  in  KP35062  to  trigger  the  GATE driver,    the    switching   frequency    is    changed according to the  load  condition. The multi  mode PWM control is integrated to simplify circuit design and achieve good line and load regulation without audio  noise  generated.  The  peak  current  limit changes  according to the  real  load condition for low standby power in no load.

KP35062  integrates  functions  and  protections  of Under  Voltage   Lockout  (UVLO),  Cycle-by-cycle Current   Limiting  (OCP),   Output  OVP,  On-chip Thermal  Shutdown, Over  Load  Protection  (OLP) with Auto Recovery Mode Protection, etc.
