5% Precision CC/CV Primary-side Offline PWM Power Switch
Description:
OB2535/OB2536/OB2
538
performance offline PWM
Power switch for low power
AC/DC charger and adapter
applications. It can achieve
5% precision constant
voltage (CV) and constant
current (CC). It operates in
primary-side sensing and
regulation. Consequently,
opto-coupler and TL431
could be eliminated.
