OB2276A High Performance Current Mode PWM Controller GENERAL DESCRIPTION OB2276A is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is th.

High Performance Current Mode PWM Controller

OB2276A High Performance Current Mode PWM Controller GENERAL DESCRIPTION OB2276A is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved. VDD low startup current and low operating current contribute to a reliable power on startup and low standby design with OB2276A. OB2276A offers complete protection coverage with auto-recovery including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), Brownout protection, VDD over voltage protection (OVP), over temperature protection (OTP), output over voltage protection and VDD under voltage lockout (UVLO). Excellent EMI performance is achieved with On-Bright p.
