KP3114 Description
KP3114 is a high Performance Switch Mode Power Supply Switcher for low power off-line application with minimum ponents 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.
