General Description

LN3C69 is is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in less than 70W range.

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 loss.

Key Features
