Introduction

AI Translation

EG1252L is a cost-effective current-mode PWM controller suitable for medium and high power flyback and forward converter applications. The EG1252L features built-in frequency jittering for excellent EMI performance. The device employs hiccup mode control for light-load and no-load conditions. The EG1252L integrates comprehensive protection features: VCC under-voltage lockout (UVLO), VCC over-voltage protection (OVP), cycle-by-cycle current limiting, input under-voltage protection, overload protection, over-temperature protection, and soft-start.
