高速PWM控制器 High Speed PWM Controller
DESCRIPON
The UC1825 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 comparators 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.
