Introduction

AI Translation

DP2293 is a high performance current mode PWM controller for offline flyback converter applications. It supports DCM and CCM operation. In DP2293, 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. DP2293 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. DP2293 is a high performance current mode PWM controller for offline flyback charger, motor driver power supply and adapter applications. The IC can support CCM and DCM operation, which is suitable for isolated power supply design that requires CV regulation of the output.
