The UTC UC3869 is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to a t.
* High voltage startup * Power on soft start reducing MOSFET Vds stress * Efficiency and minimum standby power * Frequency shuffling for EMI * Audio noise free operation * Fixed 65KHZ switching frequency * Comprehensive protection coverage
VDD Under Voltage Lockout with Hysteresis (UVLO) Cycle-by-cycle over current protection (OCP) Overload Protection (OLP) External programmable Over Temperature Protection (OTP) VDD Over voltage Protection(OVP)
