UC1825B-SP Description
The UC1825B-SP PWM control device is optimized for high-frequency switched mode power supply applications. Particular care was given to minimizing propagation delays through the parators 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.
