The Texas Instruments UC3846 is a versatile dual-ended current-mode Pulse Width Modulation (PWM) controller designed for fixed-frequency control schemes. It operates at switching frequencies up to 500kHz, offering enhanced load response characteristics and inherent pulse-by-pulse current limiting.
Key electrical features include a maximum duty cycle of 50% and a precise ±1% band gap reference. The device also incorporates features such as adjustable switching frequency, current limiting, dead time control, an error amplifier, multi-topology support, soft start, and synchronization.
Available in both SOIC (DW) and PDIP (N) packages, each with 16 pins, the UC3846 is suitable for various power supply topologies including Boost, Flyback, Forward, Half bridge, and Push-pull configurations. Its design facilitates a minimum external parts count for simpler, easier-to-design control loops.
This controller is well-suited for applications requiring efficient and stable power management, benefiting from features like automatic feedforward compensation and automatic symmetry correction in push-pull configurations.
