Product Description

Off-line, inductorless AC input linear regulator


The KP3310 is an off-line linear regulator with a compact inductance free design. By adjusting the SEL pin resistance, the KP3310 can obtain a 5V/3.3V/2.7V three-gear output voltage. The KP3310 is a simple and reliable off-line power supply solution for offset power supply.


The KP3310 integrates 650V power MOSFET, start control circuit, VDD voltage control circuit, AC signal synchronous detection circuit, low voltage difference regulator, etc. The chip intelligently controls the AC energy input to reduce the system loss, improve the system efficiency, and effectively reduce the system standby.


The KP3310 integrates complete protection functions with self-recovery function: VDD undervoltage protection, VDD overvoltage protection, output overload protection, output undervoltage protection, lightning surge protection and built-in overtemperature protection.
