KP3114

KP3114 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 KP3114 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.
KP3114 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.
