KP3205

KP320X family is a high performance PWM power switch for low power off-line application with minimum components in typical buck solution.This family has built-in high break down voltage MOSFET to withstand high surge input.

Unlike conventional PWM control, there’s no fixed internal clock in KP320X 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.

KP320X integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Output Over Voltage Protection (OVP), Over Temperature Protection (OTP), FB Abnormal Protection, Over Load Protection (OLP) etc.
