Description

HT2800S is high performance primary

sensing regulation and monolithic switching-

mode power controller which is designed for

small- power supply equipment with current

mode control. Built- in accurate CV/CC control

circuit. High integration design, a high

performance power BJT and PFM controller

and full protection circuits in single chip, to

minimize external components and save the

cost effectively. HT2800S can be simply

designed a typical flyback switch converter,

the unique driving technology promotes the

characteristics of withstand voltage and

achieves excellent converting efficiency
