      Highly Integrated Offline Current Mode PWM Power Switch
      Download

      General Description

      KP2011 is a high performance current mode PWM power switch for offline flyback converter applications.

      In KP2011 PWM switching frequency with shuffling is fixed to 65KHz and is trimmed to tight range. The IC has built-in green and burst mode control for light and zero loadings, which can achieve less than 75mW standby power.

      KP2011 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, VDD Clamping and CS Pin Float Protection, etc.
