SC2582 is a highly integrated current mode PWM
controller optimized for high performance, low
standby power and cost effective offline flyback
converter applications.
At full loading, the IC operates in fixed frequency
mode. When the loading goes low, it operates in
Green Mode for high power conversion efficiency.
At no load or light load condition, SC2582
operates in Burst Mode to minimize switching loss.
Less than 75mW standby power consumption
and very high conversion efficiency is thus
achieved.
SC2582
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.
SC2582 is offered in SOT23-6/SOP-8/DIP-8
package.
