Texas Instruments UC3825QTRG3 is a versatile voltage-mode PWM controller IC designed for high-performance DC-DC converters. This component supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. It offers positive output voltage control with a maximum duty cycle of 85% and operates within a switching frequency range of 340kHz to 460kHz. Key control features include current limit, enable, frequency control, ramp, and soft start functionality. The UC3825QTRG3 is suitable for applications requiring step-up, step-down, or step-up/down conversion. It features two outputs and is supplied in a 20-PLCC package for surface mounting. The device operates from a supply voltage range of 8.4V to 30V and is rated for an operating temperature of 0°C to 70°C. This controller is widely adopted in industrial power supplies, telecommunications equipment, and consumer electronics.
