UC3853

CURRENT MODE PWM CONTROLLER FOR FORWARD AND FLYBACK APPLICATIONS

The UTC UC3853 is a high performance current mode PWMcontroller ideally suited for low standby power. Low V DD startupcurrent make the power reliable on startup design and a largevalue resistor could be used to minimize the standby power. At noload condition, the IC operates in power-saving mode for; Peak Current Mode Control Adjustable Switching Frequency Adjustable Soft?start Timer Adjustable Internal Ramp Compensation Jittering Frequency ±6% of the Switching Frequency Power-saving mode for high standby efficiency Auto?recovery Primary OCP with 10ms Fixed Delay Auto?recovery Brown?Out Dete;

UC3853

溫度范圍為 –0°C 至 70°C 的 75kHz 雙極連續(xù)導(dǎo)通模式 (CCM) PFC 控制器

The UC3853 provides simple, yet high performance active power factor correction. Using the same control technique as the UC1854, this 8-pin device exploits a simplified architecture and an internal oscillator to minimize external component count. The UC3853 incorporates a precision multiplier/square; ? Complete 8-pin Power Factor Solution\n? Reduced External Components\n? RMS Line Voltage Compensation\n?
