Safety-Chip SC2583
SC2583 is a highly integrated current mode PWM controller optimized for high performance, low standby power and cost effective offline flyback converter applications. When the loading goes low, it operates in Green Mode for high power conversion efficiency. At no load or light load condition, SC2583 operates in Burst Mode to minimize switching loss.| Part No. | SC2583 |

DESCRIPTION
At full loading, the IC operates in fixed frequency mode. Less than 75mW standby power consumption and very high conversion efficiency is thus achieved. SC2583 offers comprehensive protection coverage with auto-recovery including over load protection (OLP), Cycle-by-Cycle current limiting (OCP), VDD under voltage lockout (UVLO), over temperature protection (OTP), and over voltage protection (OVP). Excellent EMI performance is achieved with internal frequency jitter technique. The tone energy at below 22KHz is minimized in the design and audio noise is eliminated during operation. SC2583 is offered in SOT23-6/SOP-8/DIP-8 package.FEATURES
