The UC3846N from Unitrode is a Current Mode PWM Controller that provides essential features for implementing fixed-frequency, current-mode control schemes with minimal external components. This controller offers superior performance, including improved line regulation and enhanced load response characteristics, simplifying the control loop design.
Key electrical specifications include a maximum duty cycle of 50% and a maximum operating frequency of 500 kHz. It operates within an input voltage range of 7V to 40V, with UVLO thresholds at 7.7V (on) and 6.95V (off). The typical gate drive current is 0.5A.
Topologically, the UC3846N supports Boost, Flyback, Forward, Half-Bridge, and Push-Pull configurations. It includes features such as an error amplifier, multi-topology support, soft start, and synchronization pin. The device is housed in a 16-PDIP package and operates over a temperature range of 0 to 70 C.
This controller is suitable for applications requiring efficient power management and precise control, benefiting from inherent pulse-by-pulse current limiting and automatic symmetry correction for push-pull converters.
