Data sheet of XN 1042 Current Mode PWM Controller GENERAL DESCRIPTION The tone energy at below 20KHZ is minimized in XN1042 is a highly integrated current mode PWM operation. Consequently, audio noise performance is control IC optimized for high performance, low standby greatly improved. XN1042 is offered in both SOP-8 power and cost effective offline flyback converter and DIP-8 packages. applications. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching FEATURES ■ Extended Burst Mode Control For Improved ■Efficiency and Minimum Standby Power Design loss.
