      Offline Current Mode PWM Controller with BOP and Output OVP
      Download

      General Description

      KP201B is a high performance current mode PWM controller for offline flyback converter applications. It supports DCM and CCM operation.

      In KP201B, PWM switching frequency with shuffling is fixed to 65 KHz and is trimmed to tight range. The IC has built-in green and burst mode control for light and no load condition, which meet 6th energy star requirement and achieve less than 75mW standby power.

      KP201B integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Input Brownout Protection (Brownout), Programmable Output Over Voltage Protection (OVP), On-Chip Thermal Shutdown (OTP), Cycle-by-cycle Current Limiting (OCP), Over Load Protection (OLP), Soft Start, VDD clamping and CS Pin Float Protection, etc.
