AC0030S
High performance primary sensing
regulator (PSR)
GENERAL DESCRIPTION
FEATURES
AC0030S is high performance primary
◆ Built-in 850V power BJT;
sensing
regulator (PSR) and monolithic
◆ PSR control, eliminates optocoupler and
switch power controller which is designed
TL431;
for small-power supply equipment with
◆ Accurate CV/CC control
current mode control. Built-in accurate
◆ Hysteresis over-temperature protection
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
IP chip, to minimize the peripheral components
to save the cost greatly. AC0030S can be simply designed a typical flyback switch converter, the unique driving technology promotes the characteristics of withstand
H voltage and achieves excellent converting TC efficiency
(OTP) circuit ◆ Higher efficiency and meet Level 6
efficiency standards ◆ Output voltage protection (OVP/UVP) ◆ < 100 mW no-load consumption ◆ Auto-Restart function ◆ Ultra-low start-up current ◆ Good EMC characteristic allows thesimple
EMC circuit
APPLICATIONS
◆ Intelligent mobile phone/small size tablet computer ◆ Digital cameras and other small digital
products ◆ RCC solutions Replace
