American First Semiconductor FS6823DG

FS6823DG is a current mode PWM controller with integrated high voltage power MOSFET. It could be used in sub 10W(Note 1) applications. In PWM mode, FS6823DG operates in fixed frequency which is precisely set internally.FS6823DG could operate in Extended Burst Mode at no load or light load, in which mode switching loss is minimized and the frequency is adjusted internally.

GENERAL DESCRIPTION

It could be used in sub 10W(Note 1) applications. To ensure that power supplies work quietly, the frequency is set beyond 20 KHz in Extended Burst Mode. Small current is needed when SFSP658623DF Gstasrttasrtuspuapnadnwdowrkosr,ktsh, uthsuaslarlgaergveavluaelureesriesstiosrtocrocuoldulbdebueseudsed in the startup circuit to minimize the standby power. Slope compensation circuit is integrated in FS6823DG, which improves system large signal stability and reduces the possible sub-harmonic oscillation at high PWM duty cycle. Leading-edge blanking on current sense (CS) input eliminates the signal glitch due to snubber circuit diode reverse recovery current. Frequency jittering technique is integrated in FS6823DG, which helps to achieve excellent EMI performance. FS6823DG offers complete protection functions including cycle-by-cycle current limiting protection(OCP), over load protection(OLP),VDD over voltage protection(OVP), VDD over voltage clamp and under voltage lockout(UVLO).FS6823DG is available in Pb-free SOP8 package.
