      HV-Startup Offline Current Mode PWM Power Switch
      Download

      General Description

      KP2262 is a high performance current mode PWM power switch for offline flyback converter applications; the internal HV-startup circuit is designed to reduce system startup time and standby power loss.

      KP2262 is designed with a high accurate 65KHz PWM switching clock, which also has the frequency jitter function for better EMC performance. The IC has built-in green and burst mode control for light and zero loadings, which can achieve less than 50mW standby power loss.

      KP2262 integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Over Load Protection (OLP), On-Chip Thermal Shutdown (OTP), Soft Start and VDD Clamping, etc.
