Introduction

AI Translation

EG1269 is a high-performance current-mode PWM controller designed for medium- and high-power flyback power supply applications. The EG1269 features a built-in frequency jittering function for excellent EMI performance. The chip employs green energy-saving mode and hiccup mode to control light-load and no-load conditions, achieving standby power consumption below 75mW for applications under 60W. The EG1269 incorporates comprehensive protection features: VDD undervoltage lockout (UVLO), VDD OVP, cycle-by-cycle current limiting, over-temperature protection, and soft-start.
