UC3823  
High Speed PWM Controller  
FEATURES  
DESCRIPTION  
Compatible with Voltage or Current-Mode  
Topologies  
The UC1823 family of PWM control ICs is optimized for high fre-  
quency switched mode power supply applications. Particular care  
was given to minimizing propagation delays through the compara-  
tors and logic circuitry while maximizing bandwidth and slew rate  
of the error amplifier. This controller is designed for use in either  
current-mode or voltage-mode systems with the capability for input  
voltage feed-forward.  
Practical Operation @ Switching  
Frequencies to 1.0MHz  
50ns Propagation Delay to Output  
High Current Totem Pole Output (1.5A peak)  
Wide Bandwidth Error Amplifier  
Protection circuitry includes a current limit comparator, a TTL com-  
patible shutdown port, and a soft start pin which will double as a  
maximum duty cycle clamp. The logic is fully latched to provide jit-  
ter free operation and prohibit multiple pulses at the output. An un-  
der-voltage lockout section with 800mV of hysteresis assures low  
start up current. During under-voltage lockout, the output is high im-  
pedance. The current limit reference (pin 11) is a DC input voltage to  
the current limit comparator. Consult specifications for details.  
Fully Latched Logic with Double Pulse  
Suppression  
Pulse-by-Pulse Current Limiting  
Soft Start/Max. Duty Cycle Control  
Under-Voltage Lockout with Hysteresis  
Low Start Up Current (1.1mA)  
These devices feature a totem pole output designed to source and  
sink high peak currents from capacitive loads, such as the gate of  
a power MOSFET. The on state is defined as a high level.
