DESCRIPTION  
The UTC UC3844/3845 are high performance fixed frequency  
current mode controllers that specifically designed for Off-Line and  
DC to DC converter applications with minimal external parts count.  
The differences between UC3844 and UC3845 are the maximum  
duty cycle ranges and under-voltage lockout thresholds. The  
UC3844 ideally suited to off-line applications with UVLO thresholds  
of 16V(ON) and 10V(OFF), and UC3845 has UVLO thresholds of  
8.5V(ON) and 7.6V(OFF) for lower voltage applications.  
*Pb-free plating product number:  
UC3844L/UC3845L  
„
FEATURES  
* Operation output switching frequency up to 500 kHz  
* Output deadtime adjustable from 50% to 70%  
* Automatic feed forward compensation  
* Latching PWM for cycle-by-cycle current limiting  
* High current totem pole output  
* Internally trimmed reference with under voltage lockout  
* UVLO with hysteresis  
* Low startup and operating current
