GENERAL DESCRIPTION 


CX7505 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, 

which can achieve less than 75mW standby. VDD low startup current and low operating current contribute to a reliable power on startup and low standby design with CX7505. 

CX7505 offers comprehensive protections coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), on-chip Thermal Shutdown (OTP), VDD over voltage protection (VDD OVP) and VDD under voltage lockout (UVLO), etc. Excellent EMI performance is achieved with frequency shuffling and soft totem pole gate drive 

The tone energy at below 20KHz is minimized in the design and audio noise is eliminated during operation. 

CX7505 is offered in SOT23-6 package.
