The Texas Instruments UC2846DW is a current mode PWM controller designed for fixed-frequency, current-mode control schemes. It offers features such as automatic feedforward compensation, programmable pulse-by-pulse current limiting, and automatic symmetry correction for push-pull configurations.
This controller operates at a frequency of 500kHz and supports a wide input voltage range from 6.95V to 40V. It is suitable for various topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. The device includes control features like current limit, enable, frequency control, and soft start.
Packaged in a 16-SOIC surface mount package, the UC2846DW operates within an ambient temperature range of -40°C to 85°C. Its design facilitates improved line regulation and enhanced load response characteristics, making it a versatile component for power supply designs.
Key electrical specifications include a maximum duty cycle of 50% and ±1% band gap reference. The device also features 500-mA (Peak) totem-pole outputs and supports synchronous rectification. It is designed for applications requiring efficient and stable power conversion.
