KP3310
KP3310 Offline, inductorless AC input linear voltage regulator KP3310 is a compact, inductorless design offline linear voltage regulator. By adjusting the SEL pin resistance, KP3310 can obtain three output voltages: 5V/3.3V/2.7V. KP3310 is a simple and reliable offline power supply solution for obtaining bias power supply. KP3310 integrates a 650V power MOSFET, start-up control circuit, VDD voltage control circuit, AC signal synchronous detection circuit, low-dropout regulator, etc. The chip intelligently controls the input of AC energy to reduce system loss, improve system efficiency, and effectively reduce system standby power consumption. 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, etc.
