DESCRIPTION
RS2535 is a highly integrated current mode PWM power switch. It built in patent High voltage startup, optimized for high performance, exhibit extra low standby power consumption (<30mW) and costs effective offline flyback converter applications.
PWM switching frequency at normal operation is internally fixed. At no load or light load condition, it operates in burst mode to minimize switching loss. Less than 30mW standby power consumption and very high conversion efficiency is thus achieved. Patent high voltage startup is implemented in RS2535, which features with short startup time and extra low standby current.
