Overview
HOTCHIP HT2269 Current Mode PWM Controller GENERAL DESCRIPTION HT2269 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 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.
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 design with HT2269.
A large value resistor could thus be used in the startup circuit to minimize the ...
