FEATURES  
DESCRIPTION  
Compatible with Voltage or Current Mode The UC1825 family of PWM control ICs is optimized for high fre-  
Topologies  
quency switched mode power supply applications. Particular care  
was given to minimizing propagation delays through the comparators  
and logic circuitry while maximizing bandwidth and slew rate of the  
error amplifier. This controller is designed for use in either cur-  
rent-mode or voltage mode systems with the capability for input volt-  
age feed-forward.  
Practical Operation Switching Frequencies  
to 1MHz  
50ns Propagation Delay to Output  
High Current Dual Totem Pole Outputs  
(1.5A Peak)  
Protection circuitry includes a current limit comparator with a 1V  
threshold, a TTL compatible shutdown port, and a soft start pin  
which will double as a maximum duty cycle clamp. The logic is fully  
latched to provide jitter free operation and prohibit multiple pulses at  
an output. An under-voltage lockout section with 800mV of hysteresis  
assures low start up current. During under-voltage lockout, the out-  
puts are high impedance.  
Wide Bandwidth Error Amplifier  
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 totem pole outputs designed to source and  
sink high peak currents from capacitive loads, such as the gate of a  
power MOSFET. The on state is designed as a high level.
