Description: OB2353 Low Power Off Line SMPS Switcher Freq Shuffling GENERAL DESCRIPTION OB23 53 combines a dedicated current mode PW M controller with integrated high volta ge power MOSFET .It is optimized for hi gh performance low standby power and co st effective offline flyback converter applications in sub 10W range. OB2353 P WM frequency operates in the fixed and trimmed . At no load or light load the frequency is internal adjusted, the IC operates in Extended ‘burst mode’ t o minimize switching loss. Lower standb y power and higher conversion efficienc y is thus achieved. VDD low startup cur rent and low operating current contribu te to a reliable power on startup desig n with OB2353. A large value resistor co
