Texas Instruments UC28025DWG4 is a versatile, high-performance current-mode PWM controller designed for a wide range of DC-DC converter topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. This device supports positive output voltage generation for step-up and step-up/step-down applications. Key control features include adjustable current limiting, enable functionality, frequency control, internal ramp compensation, and soft-start for robust power management. Operating within a switching frequency range of 340kHz to 460kHz, the UC28025DWG4 offers two output channels with a maximum duty cycle of 45%. It features transistor driver output types and a synchronous rectifier capability. The controller operates from a supply voltage of 9V to 30V and is specified for operation between -40°C and 105°C. Supplied in a 16-SOIC (0.295" width) surface-mount package, this component is commonly utilized in industrial power supplies, telecommunications equipment, and automotive electronics.
