KIWI IC KP2813SGA

DESCRIPTION

KP2813SGA is a quasi-resonant constant voltage controller with high power factor, low THD and primary side control. The IC has built-in high-voltage start-up circuit to meet the requirements of fast start-up and ultra-low standby consumption.KP2813SGA operates in quasi-resonant mode, which has high efficiency. The minimum operating frequency of IC can be set, which can ensure the system to work normally under the condition of ultra-light dummy load and meet the requirements of ultra-low standby consumption. The built-in output voltage sampling method can ensure the output voltage accuracy within ± 3%, even under light load conditions.KP2813SGA integrates protection functions, including VDD Under Voltage Lock Out (UVLO) and VDD Over-Voltage Protection (VDD OVP), Line Brownout (BOP), Output Over Voltage Protection (OVP), Over Load Protection (OLP), Short Circuit Protection (SCP), Cycle-by-Cycle Current Limit (OCP), Over Temperature Protection (OTP), Leading Edge Blanking (LEB), etc.
