General Description

KP321X family is a high performance Switch Mode Power Supply Switcher 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 KP321X family to trigger the GATE driver, the switching frequency is changed according to the load condition.
