APPLICATION CIRCUIT

GENERAL DESCRIPTION

HT2811H is high performance primary

sensing regulator (PSR) and monolithic

switch power controller which is designed

for small-power supply equipment with

current mode control. Built-in accurate

CV/CC control circuit, eliminates

optocoupler, TL431 and its related loop

devices. High integration design, a high

performance power BJT and PFM

controller and all kinds of protection

circuits in one chip, to minimize the

peripheral components to save the cost

greatly. HT2811H can be simply designed

a typical flyback switch converter, the

unique driving technology promotes the

characteristics of withstand voltage and

achieves excellent converting efficiency
